摘要
The disclosure provides a method for analyzing effect of a sub-band interference on imaging performance in a synthetic aperture radar, the method comprises: step S1: establishing a range impulse response model for a sub-band signal with a interference after a synthesis, and acquiring information about effect of a sub-band interference on imaging performance; step S2: performing a sub-band synthesis simulation on the sub-band signal with a interference, acquiring an simulation result of the range impulse response model to verify the validity of the range impulse response model, and establishing a relation curve between a sub-band overlap ratio and an amplitude of a false target; and step S3: simulating multi-sub-band Multiple-Input Multiple-Output (MIMO) measured data by using multi-sub-band Single-Input Single-Output measured data, and imaging the simulated multi-sub-band MIMO measured data to verify information about effect of the sub-band interference on imaging performance of the simulated multi-sub-band MIMO measured data.
