  • A novel method is proposed to estimate 2-dimensional (2-D) angles of arrival (AOAs) of wideband chirp signals in direction-dependent sensor complex gain condition. In this method, via the algebraic structure of wideband chirp signals time-varying manifold, a manifold time-frequency transform is presented to obtain closed-form 2-D angles estimation and sensor errors elimination. The efficacy of the proposed method is verified by simulation results.
