The detection of near-earth targets is difficult from a space based radar (SBR). As a result of the large velocity of the radar platform, the intense earth clutter is spread is the frequency domain and masks even relatively fast moving targets. Among the various clutter cancellation methods proposed to remedy the problem, the Displace Phase Center Antenna technique (DPCA) has attracted a lot of attention. It aims at compensating the motion of the platform to attenuate the return from stationary scatterers while allowing moving targets to be detected. A model was developed to describe the operation of space based radars employing DPCA. This model was used to determine the minimum detectable velocities of an SBR with DPCA for different sets of radar parameters and observation geometries. The results are compand with those of a pulse Doppler radar without motion compensation.
