False Target RADAR Image Generator for Countering Wideband Imaging Radars
US6624780.pdf (425.0Kb)Abstract
A system for generating a false target radar image for
countering wideband synthetic aperture and inverse synthetic
aperture imaging radar systems to prevent a selected
target from being detected by such radar systems comprises
a receiver system for producing a digital signal that represents
an incident radar signal. A phase sampling circuit is
connected to the receiver for sampling the digital signal and
providing phase sample data. An image synthesizer circuit is
connected to the phase sampling circuit and arranged to
receive the phase sample data therefrom. The digital image
synthesizer circuit is arranged to process the phase sample
data to form a false target signal, which is input to a signal
transmitter system arranged to transmit the synthesized false
target signal so that it can be received by a radar system.
