A multiple open-loop interference canceller for a rotating search radar
Abstract
This paper desribes the construction and operation of a triple open-loop interference canceller for a high PRF, high rotation rate, search radar. Experimental results show that a reduction in jamming power of up to 25 dB can be achieved when countering the effects of one, two or three jammers present in the sidelobes of the main antenna without significantly affecting target detection. The results also show substantial benefits even with strong main beam jamming.
