Abstract

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 PA₀ from an 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-ΔPA-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
