Abstract: This monopulse processor provides target position information having an RMS error which is less than that of a conventional monopulse processor. A ?±j? vs. ? processor is modified to provide a position output signal equal to the smaller in absolute magnitude of the results obtained from the ?+j? vs. ? and the ??j? vs. ? processing. A conventional monopulse processor is modified to provide an output signal having a value equal to Re(?/?)/[1+|Im(?/?)|].

Abstract: An apparatus for presenting radar target return signals having a spectrum of frequency components in a binaural audible form whereby an operator can detect a target or a plurality of simultaneous unresolved targets, determine the direction of each target relative to the radar antenna axis, and identify the type and motion of each target using only his auditory sense. The apparatus utilizes a filter to ensure that all frequency components of the return signal from each target have the same relative time of arrival at the two ears, thus binaurally localizing each target.
