A numerically robust, computationally efficient processing scheme for adaptive multipulse radar is described. Its purpose is to detect a target embedded in clutter and directive electromagnetic (EM) interference by processing the echoes received by an array of antennas on-board an aircraft or satellite. The algorithm which performs an efficient QR decomposition of the underlying space-time data matrix, may be implemented in parallel on either a triangular array of processors or using a novel lattice-type structure of smaller triangular array processors. A Monte Carlo simulation study has been performed to evaluate the performance of the processing scheme in terms of steady-state improvement factor, transient response, 2D filtering capability, and numerical robustness
