ABSTRACT:
A radar system provides a measurement of the co-linear and cross-polarization characteristics of a radar target. Vertically and horizontally polarized RF signals are selectively transmitted to a target and the co-linear and cross-polarized RF returns from the target are detected with each return being coupled to an output switch which is selectively operated to provide an output RF signal for providing either the co-linear or cross-polarized RF return. RF null circuits are provided for nulling internal system RF reflections for both co-linear and cross-polarized returns when either polarized signal is transmitted.
