摘要：

We present a preliminary simulation study of an interferometric SAR altimeter for the terrain-aided navigation application. Our simulation includes raw SAR data generation, azimuth compression, leading edge detection of the echo signal, maximum likelihood angle estimation and the Bayesian state estimation. Sour results show that radar altimeter performance can be improved with the feedback loop from the rear-end navigation part.
