An analysis of the performance of weighted integrators

In many pulsed radar systems the received signals are amplitude modulated in some known manner by virtue of the characteristics of the radar and optimum signal detection can be achieved by the use of weighted video integration. Thus in search radars the modulation is caused by sweeping the aerial beam pattern through the bearing of the target. An analysis of weighted integrator performance is made with the help of an approximation technique of considerable accuracy, and some search radar integration schemes are treated in order to demonstrate the use of the technique.
