Abstract
A radar system includes a variable delay circuit coupled between the transmitter and the receiver switch. A feedback loop including a comparator and an integrator is coupled between the receiver envelope detector and a control terminal for the variable delay circuit. The feedback loop controls the amount of delay of the receiver switch to maximize sensitivity to close range targets.
