<p>PURPOSE:To save time required for establishment of homing and to improve capability of multi-target homing by providing a device for calculating predicted distance changing rate which calculates the distance changing rate for each target, and a device for correlating distance changing rate which calculates correlation probability of the distance changing rate for each target. CONSTITUTION:A device 4 for calculating predicted distance changing rate calculates the predicted distance changing rate from predicted dimensions of position, speed and so on of each target, and outputs the rate to a device 7 for correlating distance changing rate. The device 7 conducts correlation processing of the predicted dimensions of distance changing rates for each target, and of Doppler information obtained from a radar signal processing device 2, and then the result is output to a hypothesis reliability calculation device 9. After that, by obtaining correlationship between the Doppler information and the predicted distance changing rate, recognition capability of 'Whether a new target or an already homed target or unnecessary signal?' can be much improved. In this way, time required for establishment of homing, can be much shortened and capability for multi-target homing is well improved.</p> |
