Abstract:
Matched field processing has a advantage of detection of multiple targets. But, if a strong interferer is moving fast near a quiet target, detection of the target is difficult due to the motion effect of the interferer. The motion of the interferer introduces energy spreading and results in poorer detection. A waveguide-invariant-based motion compensation algorithm was proposed to mitigate the motion effect of a dominant signal component, which is estimated by eigenvalue method. The eigenvalue method is good for a strong interferer, but not good for multiple targets. In this presentation, we will propose a steered beam processing method to mitigate the motion effect of multiple targets. We will verify the proposed method with numerical simulations and SwellEx96 data processing.
