Abstract :
An efficient 3-channel radar system is derived that provides both clutter cancellation and high resolution angle estimates simultaneously for a space-based radar (SBR). A phased array antenna divided into three DPCA (displaced phase center antenna) sub-apertures is assumed. The paper provides expressions to perform clutter cancellation and calculate monopulse angle estimates, along with simulation results to illustrate their performance
