Abstract
PURPOSE: To increase greatly the clutter suppression performance by differentiating the transmission pulse repetition cycle of the short-distance detection exclusive beam with every wave angle scanning period and then giving the correlation process to the virtual target distance to decide the true target distance.
CONSTITUTION: The beam, featuring the repetition cycle of a shorter distance than the object detection distance and a high transmission pulse repetition frequency and to be used exclusive for the short distance, is provided newly to the electronic scanning array radar. In response to this, mobile target detector circuit 16 capable of switching between the long-distance MTI filter and the short-distance MTI filter is installed newly in place of the conventional mobile target detector circuit. Furthermore, the high transmission pulse repetition frequency is differentiated with every wave angle scanning period so that the true target distance may be obtained from the reception signal with which the true target distance could not hitherto obtained since its repetition frequency is too high. And the combining correlation process is carried out for the virtaul target distance obtained in each wave angle scanning period through distance correlation circuit 17. The result thus obtained is transmitted to signal process circuit 14, and the short-distance detection exclusive output is used in preference for the detection of the short distance.
