Abstract :
The interferometer effects that result from combining SLB (sidelobe blanker) and SLC (sidelobe canceller) auxiliary antennas threaten the compatibility of the two functions within a single radar system. An investigation of techniques to reduce or eliminate these effects is presented. Descriptions are presented of the simulation models (which consisted of planar arrays and cylindrical arrays), analytical approach, and results of the study. The results from early tests of two techniques-namely aperture switching and jammer assignment or beam switching of steerable auxiliaries on a pulse-to-pulse basis during the duration of a pulse burst-unmistakably indicate that the interference effects can be reduced
