IPC: G01S17/66
Filed: 1983-08-15
Abstract: PURPOSE:To enhance initial catching capacity to an objective moving body, by multiplying the output of an objective body monitor circuit through a low band- pass filter and the angle error signal between detector and the objective body, and utilizing the obtained signal as a new angle error signal. CONSTITUTION:A catching monitor circuit 9 always monitors whether an objective body is caught or not in the visual range of a detector and, when it is caught in the visual range, ''1'' is outputted and, when not caught therein, ''0'' is outputted. LPF10 inputs the outputs signal (a) of the circuit 9 and outputs a signal (b) at constant time constant T. A multiplier 11 operates the multiplication of an angle error signal 7 and the output signal (b) of LPF10 and outputs the resulting signal (c) to a compensation circuit 12. This circuit 12 generates a rotation drive signal 8 according to a PID control rule so as to always bring the signal (c) to zero. By this method, the rotary speed of the part to be driven of a tracking apparatus 4 is suppressed low and initial catching capacity to the moving objective body can be enhanced.
