| Abstract: | The matching of the local light wavefront and signal light wavefront in the laser coherent array imaging radar system will directly affect the sensitivity and resolution of the system.The shaping processing for the coherent imaging local beam is carried out by means of the conjugate grating synthetic technique,thus the detector array can be suited and the synthetic output can meet the optimal signal noise ratio conditions. |
