ABSTRACT:
A doppler radar arrangement that is able to reject short pulses. It does so by comparing the modulus of a difference vector with the same parameter during the preceding PRI. Information corresponding to "No short pulse" or to "Short pulse detected" is stored during each pulse repetition interval. The short pulse signal is replaced by the preceding signal in the same range gate only once by comparing the stored information relating to the current i.sup.th PRI and to the preceding i-1.sup.th and i-2.sup.th PRI.
