Abstract

The method of microwave resonant compression is applied for converting relatively long low power microwave pulses into nanosecond microwave pulses of high power. A microwave resonant compressor (MRC) includes a storage volume which is resonantly excited and after the transient is over the volume is made strongly coupled to an external load. During excitation some leakage is observed as the switching element provides commonly the transition attenuation of -45...60 dB. Here two new ways for further prepulse suppression are proposed. First, an additional passive resonant cavity connected into output line decreases the prepulse power and energy about 10...12 dB. The second way is processing signals in a radar receiver. Received signals are divided and delayed relatively for a time equal to the pulsewidth of nanosecond sensing pulses. Ideally the procedure eliminate the prepulse completely.
