<p>PROBLEM TO BE SOLVED: To solve the problem of difficulty in avoiding blind velocity, while the Doppler frequency of an object target is different in the system for each antenna in the conventional case. SOLUTION: This radar system is equipped with an antenna 1, a transmitter/ receiver 2 performing frequency conversion of a transmitting/receiving signal and amplifying it, a signal processing device obtaining position information of a mobile target from a received video signal and eliminating clutter components, a tracking calculation device 4 predicting the future position of the mobile target from the position information, detecting the velocity and forming tracking target items, a beam item calculating device 6 calculating beam items from the tracking target items, and a transmitting frequency calculating device 7 calculating a transmitting frequency on the beam items, in such a manner that the Doppler frequency of the mobile target has a prescribed ratio of PRF. The transmitter/receiver 2 simultaneously transmits each transmitting frequency obtained by the device 7 and receives a reflected waves from the mobile target without depending on the moving velocity of a target of system of each antenna.</p> |
