A new method to find the direction of radar signal

The new method is called single-channel electroscan quasi-monopulse direction finding (DF) technique. It adopts the electroscan to control the commutation of the directional beams to obtain the directional pulse amplitude (PA) information. The PA, from omni directional channel is taken as a reference. The process of the PA difference among the directional beams is based on constant difference PA principle. By consulting the RF-Delta PA-DOA (Direction Of Arrival) table in the memory, the direction of radar signal is obtained. The advantages of the method are synthesized from multi-beam, PA comparison and electroscan DF techniques. Thus the system configuration is optimized, the cost is reduced and the performance is enhanced.
