ABSTRACT:
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.
