Cascaded MTI and coherent integration techniques with motion compensation
Displaced phase center antenna (DPCA) is a technique for improving clutter rejection in airborne radars which use Doppler processing. Andrews (1972) evaluated DPCA in systems that incorporate delay line cancelers. This study extends the earlier work to include coherent integration. An analytical structure is established for accommodating an arbitrary number (n) of cancelers and an arbitrary number (N) of pulses integrated. The measure of performance is the standard improvement factor I. Quantitative results are presented for various combinations of the important parameters: n, N, platform speed, and clutter spectral width. In addition, convenient compact expressions for approximating I are developed.<>
