Evaluation method of angular resolution for extreme ultraviolet telescope;

Furthermore,two means to increase the angular resolution including utilizing laser beam intensity ratio and adding more sensors are described,and the relationship between the angular resolution and lens’ parameters with different number of sensors is given.

Comparing the angular resolution with this algorithm before and after,its absolute accur.

The minimum variance distortionless response(MVDR) method for direction of arrival(DOA) is studied,and simulations and experiments show that the MIMO array can achieve better performance in target detection and angular resolution over the conventional phased arrays.
