After studying the theory of combined signal processing with acoustic pressure and particle velocity, a method of direction estimation underwater, which is based on intensity measurement using an acoustic vector sensor, is presented. In the low frequency field with kinds of line-spectra, azimuth angle estimation is achieved based on the probability density statistics and bar graph approach. It can preferably resolve the problem of left/right bearing resolution and estimate the direction of space.

By the theoretical analysis and computer simulation,several characteristics of radar signal have been discussed,such as ambiguity graph,distance resolution,velocity resolution and low probability of intercept performance.The simulations show that the hybrid signal has a "thumbtack" ambiguity graph and a better performance for the distance resolution and the velocity resolution.
