Joint multipath signals and noise reduction in passive radar

The paper considers the multipath signal and noise reduction problem in passive radar. A unified framework is provided for joint of signals both Gaussian non-Gaussian circumstances. traditional clutter cancellation methods are incorporated this corresponding to circumstance. Based on framework, a method (JRM) developed suppressing noise. Specifically, explicitly discussed. Analytical analysis proposed included. An approximate implementation JRM (approximate method) which increases computational efficiency also provided. Simulations demonstrate effectiveness methods.
