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.
Claims3
A processing technique for defining the aiming point for a data collection receiver of a data collection system by an operator comprising the steps of:
- directing a detector at rotary type aircraft to receive target signals from the aiming point;
- extracting sub-audio returns from the output of the detector to acquire signal characteristics of the target;
- amplifying sub-audio signal returns with a receiver coupled to the detector;
- converting the sub-audio signals to audible signals, which are a function of the sub-audio signals;
- comparing the intensities of various audible signals as a function of the aiming point;
- readjusting the aiming point 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.
A system for defining the aiming point for a data collection receiver of a data collection system by an operator comprising:
- a data receiver directed to the aiming point for collecting and amplifying sub-audio signals emitted from rotary type aircraft;
- converter means for converting the sub-audio signals to audible signals;
- readjusting means for readjusting the aiming point 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.
