    摘要： A pulse doppler radar having variable repetition rates, noise pulses resulting from echos received from stationary multiple-time-around objects are removed by subjecting the reflected pulses to a coherent integration modified by means of a simplified vectorial addition of the reflected pulses, using an integration circuit consisting of a plurality of filters.The signal amplitude produced at the output of each filter is individually compared to the mean value of signals produced by all other filters, and a target indication is produced when the mean value is exceeded by the amplitude of a signal from an individual filter.

    摘要： A moving window detector for a radar including adding circuits for automatic detection of moving targets wherein the components of prior art devices are substantially reduced by utilizing a digital integration circuit and a shift register with a number of storage locations and wherein the input echo signals are supplied to the input of the shift register and to the integration circuit and the output of the shift register and the integration circuit are supplied to a subtracting circuit which supplies an output to an adder of the integration circuit so as to substantially reduce the number of components over those of the prior art.
