Abstract
1. A radar detection system comprising means for generating time spaced pulses of high frequency energy, said pulses having a width equal to a/nf.sub.r, where a and n are integers and f.sub.r is the pulse repetition frequency, means for projecting said energy pulses into space, receiver means for receiving target reflected echoes of said projected pulses, said receiver means including a heterodyne mixer, a bandpass circuit connected to the output of said heterodyne mixer, and means for supplying received echo signals to said mixer, means for supplying pulses corresponding to said generated pulses in pulse repetition frequency, pulse width and frequency to said heterodyne mixer as a local oscillator signal, said bandpass circuit having a passband centered at the frequency nf.sub.r, the width of said passband being not greater than f.sub.r.
