Ip. Theron et al., COMPACT RANGE RADAR CROSS-SECTION MEASUREMENTS USING A NOISE RADAR, IEEE transactions on antennas and propagation, 46(9), 1998, pp. 1285-1288
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.
