A New Kind of RMA for Translational Invariant Bistatic SAR Configuration

摘要：

The range migration algorithm suitable for bistatic sAR is proposed. The phase term of bistatic SAR point target reference spectrum is no longer linear for the range coordinate of the point target because the distance respectively from the transmitter and receiver to the target are not equal and this make it difficult to use the typical RMA to process bistatic sAR signals. According to this,this paper presents a new kind of RMA suitable for bistatic SAR working in translational invariant mode based on a new expression of bistatic SAR point target reference spectrum,and the precision of this approach is only influenced by the precision of interpolation and the division of bistatic SAR azimuth Doppler frequency.Finally a raw data simulation verified the validity of the approach presented here.
