Binary Quantization of Signal Amplitudes: Effect for Radar Angular Accuracy

An investigation made by P. Swerling [4] determining the limits that receiver noise imposes upon the accuracy with which the angular position of a target may be estimated by a pulsed search radar, is extended to determine additional accuracy limitations imposed by the quantization of signal strengths prior to angle estimation. This analysis follows that of Swerling in form. The results are presented in graphs. For many cases of practical interest, the additional limitation in accuracy may be neglected.
