Claims

[Scope of utility model registration request]

A phased array antenna that can electronically scan an antenna beam while keeping the antenna surface fixed; a transceiver that outputs transmission signals to the phased array antenna and performs video processing on received signals from the phased array antenna; A constant false alarm target detection device that detects targets while always maintaining a constant false alarm in response to video signals from the aircraft, and predicts the position of the tracked target based on target data detected by the constant false alarm target detection device. A tracking radar device comprising a tracking signal processing device and a pulse hit number controller that controls the number of pulse hits to be transmitted to a tracking target based on predicted position data of the target from the tracking signal processing device.
