The azimuth super resolution is a technique problem which has been explored for years in the field of radar. The L2 norm regularization method was used for the solution, because of the ill-condition encountered in the solution process. L1 norm regularization model was also established for the lack of L2 norm method and the sparse nature of the target signal. In order to improve the computational efficiency,...
The sea clutter simulation scheme is made based on the sea surface model and two-scale scattering model. the amplitude distribution of the sea clutter is analyzed, the result shows that the scheme used in the article could generate suitable sea clutter series, the simulated sea clutter is in accord with statistical properties of real one, the feasibility of the sea clutter simulation which uses the...
Azimuth resolution of Missile-borne synthetic aperture radar(SAR) is affected by the trajectory and look angle. In order to acquire the fixed azimuth resolution within a minimum time for SAR imaging seeker, a new approach of solving optimal control problem, that is, Gauss Pseudospectral Method(GPM), is proposed to optimize imaging phase trajectory of Missile-borne SAR. First of all, optimization model...
