。 It not only has target search and tracking functions, but also
A radar device that has the function of detecting the water column caused by the impact of artillery shells has a transmitting and receiving antenna that emits the transmitted radio waves to the outside and receives reflected waves from the target and the water column caused by the impact of the artillery shell, and creates a high-frequency power pulse. a transmitter section that performs switching between transmitting radio waves from the transmitter section and receiving radio waves from the antenna; and converting the frequency of the received radio waves input from the transmitter/receive switch section to an intermediate frequency. a frequency mixer that performs this, a local signal generation section that creates a local signal for converting the received radio wave to an intermediate frequency, a receiver section that amplifies the output of the frequency mixer and then outputs it as a video signal, and the receiver a display section that receives the output from the section and displays the water column due to the impact of the target and the shell; a switching section that is in the tracking mode and switches over at a certain period of time; and a switching section that is in the tracking mode and displays the video signal within a certain period of time. a sampling and holding section that performs sampling and holding; a comparison section that receives the output of the sampling and hold section and compares it with a video signal outside a certain period of time in tracking mode; and a video signal that receives and displays the output of the comparison section. A radar device comprising an internal water column display section.
