<p>PROBLEM TO BE SOLVED: To detect a fixed target and multiple moving targets including low- speed targets, and to guide missiles to multiple targets or a single target by automatic selection by detecting the targets moving at a low speed, specifying the target, and controlling the antenna principal axis toward the target direction. SOLUTION: The transmission signal generated by a transmitter 2 is radiated to targets 5 by an antenna 4, and the reflected reception signal is phase-detected by a receiver 6 and is converted into the video signal containing the information such as the amplitudes and positions of the targets 5. Two image data of the targets 5 having a time difference are generated by a low-speed moving target detection section 13, and multiple targets 5 moving at a low speed are detected via subtraction. A target judgment section 14 judges single/multiple targets and the degree of threat and specifies a target. The error angle between the reflecting direction of the target and the principal axis direction of the antenna 4 is selected to calculate angular velocity by an angle error operation section 15. The angular velocity corresponding to the antenna swing angle is calculated by a gyroscope 10, and an antenna controller 11 controls the antenna principal axis toward the target direction using both angular velocities.</p> |
