摘要: A system and method of processing data in a sensor which receives signal returns from pulsed coherent transmitted signals are at pulse repetition rate with interval (PRI). The includes providing (202) range-filtered response to the received returns; formatting (204) successive sets during postdetection integration (PDI) into plurality overlapping (CPI) sequences; performing (212) FFT on CPI sequences provide transformed (214) range-sample (218) noncoherent (NCI) output processed over range trajectory accordance hypothesized radar-target gain-enhanced data. derived is updated compensation no more often than once per PDI interval.
