Process for range measurement with a pulse radar of high pulse repetition frequency

摘要: With a frequency-agile pulsed doppler radar with high pulse repetition frequency (HPRF) in the unambiguous velocity region, order to measure range of target complex time signal derived from echo signals coherent processing interval (CPI) is transformed into domain, spectrum multiplied by bandpass function mean coinciding target, and product back signal. The real envelope this re-transformed displays definite leading edge steady state which travel can be estimated. Particular advantages may for set plurality agile transmitter/receivers operated at same different frequencies, whose switching times are time-staggered.
