Abstract : The off axis angle detector of a radar is sampled at discrete intervals by a special purpose digital computer. Each sample is directed to one of a plurality of registers in accordance to the angle indication of the sample. Each register being a counter which will give an output when it is in an overflow condition; therefore, each register acts as a threshold device. Upon one register overflowing and giving an output of that indication, the sample process is stopped and the output of the register is sent to a converter to indicate the direction of the jammer. This is done both for the azimuth and elevation angle of the radar receiver. (Author)
