A directional sensing algorithm is proposed employing doppler radar and low-complexity 2-D IIR spatially bandpass filters. The speed of the scatterer is determined by the frequency shift of the received signal following down-conversion. The downconversion is done by mixing it with the instantaneous transmitted signal. The direction of the scatterer is determined by the means of 2-D plane-wave spectral...
Several methods have recently been developed to prevent a radar from being used by a non-cooperative bistatic radar receiver as an illuminator. The main requirement for non-cooperative bistatic operation is the estimation of a coherent reference signal which is typically obtained by interception of the direct path signal via the sidelobes of the illuminator. These techniques are based on the idea...
