ABSTRACT:
A method for radar target detection and angle estimation in the presence of jamming includes the steps of receiving a signal from a radar array having elements arranged in rows and columns; performing deterministic row-based beamforming on the received signal to obtain row sum azimuth beams; performing deterministic column-based beamforming on the received signal to obtain column sum elevation beams; performing one-dimensional maximum likelihood estimation on the row sum azimuth beams to obtain an estimated target elevation angle and an adaptive array sum azimuth beam; performing one-dimensional maximum likelihood estimation on the column sum elevation beams to obtain an estimated target azimuth angle and an adaptive array sum elevation beam; and performing target detection based on the adaptive array sum azimuth beam and the adaptive array sum elevation beam.
