Abstract

PURPOSE:To secure the effective elimination of the clutter for the video signal and then decrease the loss of the target as well as the deterioration of the resolution, by carrying out the discrimination between the target and the clutter with every detection of the signal and by noticing the distribution state of the detection signals within the monor territory near the signal. CONSTITUTION:The control signal is produced by applying the radar trigger signal 2 and radar antenna azimuth signal 3 to timing control circuit 9. On the other hand, radar video signal is applied to quantizing circuit 4 to produce the output with every quantizing distance to the signal which satisfies the fixed threshold conditions. Memory circuit 5 memorizes the quantized video up to m-pin from the present and in the azimuth direction and then delivers the data of n-pin and m-pin in the distance and azimuth directions each every time the signal is received from circuit 4. This distributions are compared with the distribution set previously through discriminating circuit 6, thus performing the discrimination between the target and the clutter.
