  • The general relative range model for non-linear trajectory is built firstly, followed by the maneuver induced phase errors analysis. The quantitative conditions of ignoring these errors are deduced later. Then this paper concerns on the issue of missile-borne SAR on the trajectory with diving maneuver: the characteristics of signals are analyzed and a range Doppler based algorithm is presented according to these characteristics. Compared with the range Doppler algorithm under linear aperture, the new one just modifies some phase correction factors and needs no additional complexity owing to nonlinear aperture.
