[0072] In this embodiment, taking the positioning of a ship target in a cluttered ocean environment as an example, an exemplary implementation manner of the present invention is described in detail.
[0073] figure 1 A schematic diagram of the structure of a dual airborne SAR for target collaborative imaging stereotaxic positioning proposed by the present invention, mainly composed of two SAR radars with two fixed-wing unmanned aerial vehicles as platforms, and the two unmanned aerial vehicles are in the same direction in the target area Fly both sides while imaging the scan area.
[0074] figure 2 The general flow chart of a kind of dual-airborne SAR that proposes for the present invention is to the stereotaxic positioning of target cooperative imaging, and concrete implementation steps are:
[0075] The first step is to use the range Doppler imaging algorithm to perform high-resolution imaging on the echo data of the sea surface scanning area received by the two airborne ...
