Abstract
It is significant to estimate the waveguide invariant and the moving target parameters accurately, because the former is a physical parameter demonstrating the propagation characteristics and environmental characteristics of the ocean, while the latter is the foundation of passive ranging and target recognition. Hough transform based waveguide invariant and the moving target parameters estimation algorithm in which neither the distance information nor the closest point of approach of the moving target is needed, is proposed combining LOFARgram and bearing-time records, more attentions are paid to the joint estimation of the waveguide invariant and the heading angle. And the moving target parameters also include the ratio of range at the closest point of approach (CPA) to source speed and the time at CPA. The feasibility of the parameter estimation algorithm has been validated by the simulation researches, which also indicate that the parameter estimation algorithm has high estimation precision.
