Abstract

This article discusses the problem of active detection and estimation for the elevation angle of a target in a homogeneous shallow sea environment, where a method using active detection on virtual time reversal (ADVTR) is proposed to solve the estimator performance decline problem caused by multipath and clutter. Unlike the conventional passive target estimation method ignoring the multipath effect, the ADVTR method will take full account of the multipath which exploits active detection (AD) to estimate channel, and virtual time reversal (VTR) to realize focusing in a computer to increase the signal-to-noise ratio (SNR) after the source-receive array (SRA) receives the reflected signal of the target. Furthermore, the Capon algorithm is adopted to compare the performance of ADVTR estimator and conventional one. Numerical simulations demonstrate its superior performance than the conventional estimators.
