Abstract:

A two-stage signal processor which may be used to process the received waveform from a large time bandwidth radar transmission is described. This two-stage receiver concept combines the advantages of the high speed capability of analog equipment and the versatility of digital equipment. It is applicable to a wide variety of transmitted waveforms which may be approximated by a sequence of discrete frequency components. The capability of this two-stage signal processor to resolve multiple closely spaced in range targets is demonstrated and the influence of target motion and receiver noise are examined. Two convenient approximations having good accuracy in the probability range of interest are described and compared numerically with results known to be exact. Author
