Abstract
A technique for narrowing the antenna pattern based on joint spatial-temporal processing of signals received at successive moments of time by spatially separated receiving antenna arrays of a quasi-monostatic decameter early warning radar system is presented. The technique application makes it possible to increase the probability of detecting objects located outside the line of sight against the background of powerful interfering interference caused by both the propagation medium and reflections from the underlying surface. The implementation of the methodology will improve the reliability of determining objects located by decameter radar systems.
