ABSTRACT:
An aiming point system and technique for defining the aiming point of a d collection receiver used by an operator. A data receiver is directed to the aiming point for collecting and amplifying sub-audio signals emitted from rotary aircraft. The sub-audio signals are converted to audible signals by a voltage to frequency converter. The aiming point is readjusted manually or automatically in response to the sub-audible strength of the audible signal to obtain at least a substantial proportion of the target signature of the rotary type aircraft. The data collection receiver may include binoculars with a silicon photo detector and pre-amp within one of the binocular eyepieces.
