LPI Radar Systems with Spatial Feedback

The radar system with spatial feedback is considered. In this system there are self-oscillations, if the system is closed through a space of the signal radio-path and the target. When the target is absent (system is not closed), transmitter output power of the noise signal is insignificant, and that complicates detection of the radar radiation. In the report principles of such system functioning and results of tests on the real targets are stated.
