Abstract :
For the problem of far-near effect, a sum-difference multi-beamforming with null broadening and mainlobe keeping is proposed. With measurements of direction of arrivals and ranges, orbits of spatial targets are determinated by coordinate conversion, Laplace iteration and six parameters estimation. Simulation results demonstrate high precision of the method.
