FIELD: radio engineering, communication.
SUBSTANCE: in the method of two-step radar target detection based on probing the direction in the second step, if the target is detected in the first step, according to the invention in the first step they allow the range targets, and in the second step - speed targets, while in the first step, they use the probing signal with high resolution in range, and in the second - in speed, while in the first step they use broadband probing signal, and in the second step - narrowband. In addition, in the second step, a sequence of signals with ambiguous range or reduced range resolution is used for probing.
EFFECT: reducing the time spent on tying target tracks and increasing the reliability of maintenance by reducing the size of the primary capture pulse gate, possibility of detecting especially dangerous high-speed targets in the first review.
