Abstract

PURPOSE:To secure an accurate decision for tracking whether or not the antenna direction is within the peak region to the target direction by means of a simple- structure device. CONSTITUTION:In case the peak region is set up 5, peak setting circuit 3 delivers no output when the contents of up-down counter 2 is within N - 1, N and N + 1. And outside these ranges, FF11 and counter 4 are reset with gate 12 and 13 turned off until the pulse showing the level reduction of the reception signal is supplied 15. When the target is kept at N with no effect of fading, the antenna direction repeats the fixed driving patterns with the contents of counter 2 being within N + or - 1. And the positive and negative command pulses are supplied to counter 4 from gate 14 while no output is delivered from circuit 3, and the peak decision signal is delivered 40 when fixed number n >= 4 is obtained. The antenna direction is identical to the target while output 40 is delivered. Thus, the highly reliable peak decision signals can be obtained.
