Abstract

This paper presents some further results on the STAP approach using sum (Σ) and difference (Δ) beams, including the desired characteristics of the ΣΔ-beampatterns, comparison of the ΣΔ-STAP and ΣΔ-DPCA, and an evaluation of its performance for three different Δ beams. It is shown that: (a) ΣΔ-STAP is not sensitive to the sidelobe textures of the ΣΔ-beampatterns if the receive and transmit antennas have reasonably low sidelobes; (b) ΣΔ-STAP can be viewed as a natural extension of ΣΔ-DPCA with the added adaptivity to overcome the DPCA shortcomings; (c) in addition to the azimuth difference (Δ_a) beam, elevation difference (Δ_e) and azimuth-elevation difference (Δ_ae) beams are two useful candidates, especially when more spatial channels are needed.
