摘要
An apparatus and method for detecting the polarisation of signals reflected from targets immersed in clutter are disclosed. Signals reflected from targets illuminated with quasimonochromatic electromagnetic signals such as FMCW radar are received by antennae (21,25) responsive to orthogonally polarised components of the reflected signals. These received orthogonal signal components are then analysed in a processor (12) which detects the polarisation of the reflected signal by estimating the Stokes parameters for the reflected signal, The estimated Stokes parameters may then be used to generate detection criteria that are compared with a predetermined threshold level. The presence of the target is indicated when the detection criteria level exceeds the level of the predetermined threshold.
