A new method for direct signal recover in non-cooperative bistatic radar

The direct signal which includes noise and multipath clutter greatly declines the performance of the non-cooperation bistatic radar system. To mitigate this problem, a new method based on three-sensor array for direct signal recover in non cooperation bistatic radar is proposed. The expression of recovering direct signal from white noise and multipath clutter is analyzed in detail. Statistical performances of the method are provided by computer simulation. The theoretical analysis and simulation result shows that the new method can recover the direct signal effectively from noise and multipath clutter.
