Claims

[Scope of utility model registration request]

A radar device having functions of searching, detecting, and tracking a target and receiving echoes from the target includes a transmitting/receiving antenna that emits high-frequency power pulses to the outside and receives reflected waves from the target, and the high-frequency power A transmitter section that generates pulses, a transmission/reception switching section that switches between transmission and reception, a mixer for converting into an intermediate frequency, a receiver section that outputs the output of the mixer as a video signal, and a video signal from the receiver section. a video signal processing unit that processes the signal;
an R/F scope that projects the video of the video signal processing section on the scope; a loop coupler for extracting a part of the high frequency power pulse from the transmitter section; and a loop coupler for delaying the high frequency power pulse from the loop coupler for a certain period of time. It consists of a delay select, which combines a delay line, and an operation section for the operator to operate the delay select.A portion of the high-frequency power pulse from the transmitter section is taken out by a loop coupler, and an arbitrary A radar device characterized in that an operator can freely set a desired pseudo video position by selecting a day line.
