Efficient Target Detection and Joint Estimation of Target Parameters With a Two-Element Rotating Antenna

An algorithm is proposed for the detection and joint estimation of target parameters for a radar with a two-element rotating antenna. Rotation of the antenna introduces unwanted effects, which may cause inaccuracy in the parameter estimation. Target detection is performed by adding the processed data from two sensors. Joint estimation of range, Doppler, and direction of arrival (DOA) is carried while compensating the effects of antenna rotation. The detection performance is analyzed in terms of the receiver operating characteristics. Analytical expressions of Cramer-Rao Bound for Doppler, the range and DOA are derived. Computational complexity is also discussed. A simulation demonstrates and verifies the proposed algorithm and its analyses.
