Spin echo matched filter ECM detector |
摘要 |
A system for determining the use of an ECM jammer against a bi-frequency radar utilizing a spin echo matched filter. Portions of two simultaneously transmitted radar RF pulses of different instantaneous carrier frequencies are coupled to a non-linear element which produces a composite pulse signal containing predetermined intermodulation product frequencies. This composite pulse signal is utilized as the input pulse to a spin echo system which has a locally generated postset pulse applied a predetermined time thereafter. The radar return signals are coupled to the spin echo system which produces a spin echo correlation signal upon the reception of an ECM radar return pulse which inherently contains substantially the same predetermined intermodulation product frequencies.
