A hybrid SAR processing method for data collected using a stationarybistatic receiver

摘要

This paper introduces a method to process bistatic data collected in a configurationwhere the receiver is stationary and the transmitter has a constant velocityand constant altitude. The signal processing uses a standard Fourier-basedconvolution to achieve the bulk of the SAR processing followed by fast, timevaryingfiltering to correct residual e A simulation is used to compare the proposedmethod with the method of non-linear chirp scaling.rrors. Theoreticalanalysis and simulated data are used to demonstrate the approach.
