438 Radar shot

Lin Yuan looked at the radar screen and exclaimed, "Why is this?" ”

Li Kai asked blankly, "What's wrong?" Is there something wrong? ”

At this time, Ma Zhiliang walked over from the side, smiled when he saw the computer screen, and said, "Why do you use such an ancient display interface." ”

Lin Yuan smiled: "That's right, there are so many advanced display modes that you don't need, you have to use the oldest." ”

There are many kinds of display screens of the original radar, different display screens are used according to different purposes, and the J-25 airborne radar is equipped with the most advanced raster scanning display, which has the general imaging effect of a TV, and can be converted between a variety of display screens, and the parameter information of the target can also be superimposed on the screen.

The A-type distance display only has radar echo information on the A-type distance display, and even the distance will not be displayed on the radar screen, and the radar operator needs to read out the time of the echo round trip according to the scale mark on the screen, and then calculate the target distance according to the speed of light.

The same is true for the P-type azimuth display, it takes the radar as the center of the circle, and the light sweeps through the circumference of 360 degrees, if there is a radar echo around the circle, there will be bright spots on the display, but the radar system will not display the target orientation by itself, and the operator needs to read the bearing according to the dial on the screen.

Li Kai smiled: "I prefer the old monitor, captain, do you know the way?" It's more participatory, but if the degree of automation is too high, the radar operation becomes a reading on the screen, so what's the point? ”

Lin Yuan smiled and said: "The Japanese minesweepers have already entered the river, and now there is a heavy fog on the river, and the means of optical detection are not good, it all depends on our radar." ”

Li Kai said: "No problem! I'll switch the radar screen back now. After Li Kai finished speaking, he typed the command "Switch Integrated Display" on the keyboard, and this process only needs to press a key on the plane, but now there is no such condition, so you can only type the command yourself.

After the command was entered, the radar screen suddenly became messy, and it was full of messy light spots, Li Kai looked at the screen and said in surprise: "Eh, what's going on?" Could it be that the radar system is malfunctioning? ”

Lin Yuan said helplessly: "You didn't start target detection, it's all clutter, you get out of the way, I'll come." ”

Li Kai asked in surprise: "Captain, do you also understand this?" ”

Lin Yuan said: "When I was flying the J-25, I watched the screen of this radar every day, and I couldn't be more familiar with it. Lin Yuan sat in front of the computer and entered the command "Moving Target Detection On" on the keyboard, and soon, the messy clutter on the screen disappeared, replaced by four clear light spots.

The so-called "moving target detection" is the killer weapon of the radar in detecting ground or sea surface targets, simply put, because the ground and sea surface are not moving, so their echoes at different times are roughly the same, if the echoes at different times are subtracted, you can filter out those ground or sea surface clutter, and get the information of moving targets.

Lin Yuan entered the "tracking mode on" command, the tracking mode is used to guide the airborne missile to attack the target, in this mode, the radar can calculate the position of the target at the next moment according to the speed and acceleration of the target that has been mastered, and then guide the missile to hit the target.

Lin Yuan entered the information display command again, and soon, the speed, direction, distance and other information of the Japanese minesweeper were displayed on the radar screen, Lin Yuan thought to himself: "Which one to hit first?" He looked at the position of the enemy ships, and they were still working in groups of two to carry out minesweeping operations, and the group behind was diagonally below the group in front. Lin Yuan then decided to hit the group behind them first, so that the group in front couldn't escape if they wanted to turn around and escape, Lin Yuan ordered Yao Feng: "Prepare for the cloud burst bomb, launch it alone!" The distance is 3.1 km, and the azimuth cave is 37! ”

Yao Feng quickly sent back the news: "Ready, ready to launch at any time!" ”

Lin Yuan was just about to give the order to launch, when suddenly, ten light points appeared on the radar screen, and these ten light points quickly approached the Japanese minesweeper behind, Lin Yuan was startled and thought, "What is this?" So he said, "Wait a minute, don't launch yet." ”

Li Kai on the side also asked, "What is this?" ”

Lin Yuan shook his head and said, "I don't know how to do it, why did it suddenly come out?" Could it be clutter interference? ”

Li Kai said: "Probably not, clutter can't be like this." ”

Lin Yuan thought for a while and said: "I know, this is the ship of the Qing army, they attacked, I told them, don't attack without my order, why don't they listen!" The lethal power of the cloud explosion was very powerful, and if they were so close, they would definitely be injured by mistake. ”

The light flickered for a while and then disappeared, and Lin Yuan knew that at this time they were already very close to the Japanese minesweepers, and the radar could not distinguish which ones were them and which were minesweepers.

If the cannon is fired, it will injure its own people by mistake, and if the minesweeper is allowed to open up a channel, the enemy may open up a landing ground in the rear of the side. ”

This target is the minesweeper in front of the Japanese army, Yao Feng then turned the direction of the artillery, and then fired the artillery, the shells whistling towards the minesweeper, in order to be able to load more gasoline in the bomb body, so Luo Chaoying's design of the cloud burst bomb uses a "short and thick" bomb body, such a bomb body volume is relatively large, but also sacrifices some ballistic performance, so the range is shorter, but it is more than enough to hit the minesweeper on the river.

The shells drew a beautiful arc in the fog, and all the attention of the Japanese minesweepers on the river was underwater, minesweeping was a very dangerous job in any era, and the minesweepers could not determine whether there were mines on their routes, and whether their draft was shallower than the fixed depth of the mines, so the Japanese soldiers on the minesweepers were silently praying to Amaterasu, hoping that the spirit could bless them with safety.

The shell designed by Luo Chaoying uses a time fuse, and Yao Feng sets the detonation time according to the target distance, but the environment in which the shell flies is always beyond human control, so the detonation time of the shell is slightly later, and when the shell detonates, it has already flown more than ten meters past the minesweeper.

At this moment, the fuse detonated the primary charge, and the primary charge immediately exploded the shell, blowing up dozens of kilograms of gasoline contained in it into the air, the explosion did not produce a spark, and the action time was extremely short, so the gasoline was not ignited, and when a large amount of gasoline was dispersed into the air, the secondary charge detonated.

The secondary charge was used to detonate gasoline, and in an instant, a huge fireball illuminated the clouds, and the bright yellow light was shrouded in the ru-white mist, which was extremely dazzling.

The burning produced a heat of thousands of degrees, and several Japanese soldiers standing on the deck operating machine guns suddenly screamed, the heat burned their skin, ignited their clothes, and turned them into terrifying humanoid torches.

The Japanese soldiers screamed and jumped into the river, the wooden outfitting on the boat was also ignited, and several large fires suddenly rose on the minesweeper, and at this moment, another shell followed, this time the shell exploded next to the minesweeper, and a huge fireball instantly enveloped the minesweeper.
