COMPACT RANGE RADAR CROSS-SECTION MEASUREMENTS USING A NOISE RADAR

This paper discusses the measurement of radar cross section (RCS) with a very low-cost system that transmits band-limited random noise over the band from 1.0 to 4.0 GHz, The received signal is correlated with a delayed version of the transmitted signal, A variable delay line is u sed to obtain the response at various delay times. This yields the rad ar target impulse response as a function of delay, This can be transfo rmed to yield both the amplitude and phase of the scattering matrix in the frequency domain.
