Assistant apparatus for improving radar signal detection performance

An assistant apparatus for improving radar signal detection performance, the assistant apparatus comprising:

• a radar signal receiver adjusting a radar candidate signal received through a reception antenna to a predetermined magnitude and filtering out a signal other than the radar candidate signal;
• a radar signal analyzer receiving the radar candidate signal from the radar signal receiver and determining whether or not the radar candidate signal is a preset radar signal;
• a radar signal production controller generating a control signal for an assistant apparatus production signal or an assistant apparatus reproduction signal on the basis of at least one of pieces of information on a type, a bandwidth, and a period of the radar candidate signal received from the radar signal analyzer;
• a radar signal producer activated by the radar signal production controller, generating the assistant apparatus production signal or the assistant apparatus reproduction signal according to the control signal of the radar signal production controller, and transmitting the assistant apparatus reproduction signal or the assistant apparatus production signal to the outside through a transmission antenna;
• and
• a delay compensator compensating for a time delay of the radar signal received from the radar signal receiver by adding a preset magnitude and outputting the resulting radar signal,
• wherein the delay compensator computes an amount of change in a beat frequency that corresponds to the time delay, and performs up-conversion of the amount of change in the beat frequency through a mixer.
