基于逆抛物方程法的有源目标探测定位

Wave propagation in irregular topography and inhomogeneous medium environment can be calculated via split step Fourier Transform algorithm, the inverse parabolic equation method could effectively position the source location in complex environments, however, directly extend this algorithm to the field of active radar target detection will meet several difficults.This letter combines the two-way parabolic equation method, time reversal adaptive interference cancellation algorithm and inverse parabolic equation,the combined algorithm have the ability to eliminate the background clutter echo effectively and positioning accuracy can be validated by numerical simulation.
