Claim 1:
2. The sparse optimization method based on cross-shaped three-dimensional imaging sonar array according to claim 1, wherein, the introduction of an array element position disturbance into the simulated annealing algorithm comprises:
when the selected array element weight coefficient is not 0, that is, the selected array is in the on state, caching (ωtemp) the array element weight coefficient and the current array element position pxy=(xm, yn);
closing the array element, updating the array element weight coefficient matrix W and the number of array elements A, and calculating the energy function;
when the energy function decreases, accepting the state and selecting the next random array element; and
when the energy function increases, turning on the array element again, and the weight coefficient adds a random disturbance within a certain range, and a disturbance is added to the original position pxy of the array element at the same time.
