Multipolarisation FM-CW Doppler radar signal processing for nondistributed targets

The Delft FM-CW radar is used to characterise radar targets based on their polarisation parameters and Doppler velocity. Dedicated polarisers allow the radar system to have one receiver only. The domain of the polarisation information interferes with the domain of the Doppler-velocity information. To split these domains and to retrieve the target parameters, a specific processing approach has been developed. The method has been implemented to run on one or more array processors, which are used as preprocessing units on a host computer. Besides the mathematical outlines of the method, the structure and organisation of the processing units are discussed in the paper. Finally, some preliminary results of real-time performance measurements are shown
