ABSTRACT:
A miss distance indicator data processing and recording apparatus compris an antenna which receives an RF missile telemetry signal from a missile attempting to intercept a target and a translated RF missile telemetry signal from an AN/DRQ-4 miss distance indicator which is on board the target. A first telemetry receiver filters, amplifies and down converts the RF missile telemetry signal to a first predetection carrier signal, and a second telemetry receiver filters, amplifies and down converts the translated RF missile telemetry signal to a second predetection carrier signal. The first and second predetection carrier signals are then supplied to an analog magnetic tape recorder which records the signals. The first and second predetection carrier signals are also supplied to a double balanced mixer which is connected to a frequency analyzer. The double balanced mixer generates a difference frequency signal which includes doppler shift and frequency offset and then supplies the difference frequency signal to the frequency analyzer. Time data is also supplied to the frequency analyzer by a time code source. The frequency analyzer displays a plot of frequency versus time which is used to accurately determine miss distance which is the distance the missile misses the target.
