Abstract
A multistage median cascaded canceller is introduced as a hybrid combination of the multistage Wiener filter (MWF) and the recently introduced median cascaded canceller (MCC). The hybrid processor is configured for radar space-time adaptive processing and tested using measured airborne radar data from the MCARM database as well as using simulated airborne radar clutter and jamming data. Results show the hybrid processor maintains a high signal-to-interference-plus-noise ratio and exhibits a mixture of useful characteristics from the two separate processors. Optimal rank reduction capability from the MWF portion is retained and robustness to targets/outliers and non-stationary data are attributed to the MCC portion. In addition, valuable synergistic features are discovered, such as an order 15 dB lower average azimuth-Doppler sidelobe level in the adapted pattern, compared to the MWF.
