Abstract :
In this paper several factors affecting the beam steering performance of laser phased array radar are analyzed completely, also simple models for some typical factors are developed. Then, a new method based on iteratively modifying the output phase pattern of liquid crystal phase shifters is proposed. Using this method, the influence of factors can be compensated to some extent; the steering angle accuracy and efficiency with laser phased array radar can be improved. Through the simulation, the error of steering angle can be reduced three orders of magnitude, and the efficiency can be increased almost 30% after 10 iterations.
