Optimization method of MIMO-OTHR target tracking trajectory

The invention provides an optimization method of an MIMO-OTHR target tracking trajectory. The optimization method comprises the following steps: receiving an echo signal, and performing centralized preprocessing on the echo signal; performing dimension reduction whitening processing on the preprocessed echo signal, so as to reduce the subsequent processing calculation amount; randomly initializingan unmixing matrix, maximizing mutual information of the received signal and an estimated value thereof, and performing calculating to obtain an unmixing matrix W by utilizing a stochastic gradient algorithm; and solving an estimator of a real track through a reversible nonlinear function by using the unmixing matrix. According to the multi-mode tracking trajectory fusion method based on the Informax algorithm, MIMO-OTHR four-mode echoes based on a two-layer ionosphere model are fused, the target tracking performance of a radar is improved under the condition of strong interference, and the effect is superior to that
