Abstract
According to the character of Passive Radar based on DTTB illuminator, spatial filtering is used to suppress the direct-path interference. The adaptive beamforming algorithms combined with broad null are adopted in echo receiving channel. To reference channel, the improved structure of general sidelobe canceller to realize the adaptive beamformer is used, simultaneity which is combined with the broad null algorithm. The simulations based on the DTTB signal show applying the proposed method has better the performance of target detection.
