Software defined radio for noise and passive RADAR processing
Abstract
Noise RADAR uses the spectrum spreading capability of phase modulation to imprint a known pattern on the carrier. By correlating the surveillance antenna measurement – aimed at targets and directed away from the emitter – with the reference signal transmitted by the
emitter or the copy of the pseudo-random sequence, time delay and target motion induced Doppler shift are computed to map the range-Doppler distribution of targets. Rather than using a dedicated emitter, existing non-cooperative emitters can be advantageously used in
the passive RADAR approach of similar concepts. Fourier-transform based correlation is demonstrated using GNURadio.
