The use of high speed FIFO chips for implementation of a noise radar

An ultra wide band spread spectrum radar (a noise radar) can be built using a system that generates two wide band spread spectrum (pseudo-random) waveforms. One waveform is transmitted by the system and one waveform is used to correlate against the received signals. Because of system dispersion, propagation channel dispersion and radar target dispersion, it is often appropriate for the receive correlation waveform to be of a different form than that of the transmitted waveform. Thus a noise radar often needs to be able to generate two different wide band waveforms with controlled differential delay time. This paper will discuss the implementation of such a system using commercially available FIFO microchips.
