Warhead impact telemetry system

The designs of the shock absorbant system, circuitry and test procedures for a warhead telemetry system capable of withstanding 50 g for 11 msec are detailed. Foam layers were placed ahead of the telemetry unit after a zone of borosilicate glass microspheres. Numerical models were developed for the expected shock pulse on the components during impact. The telemetry system was designed under the assumption of a 10 dB SNR at the receiver and 40 dB SNR at the discriminator. The entire unit was tested on a vibrator table while sine waves were fed into the subcarrier oscillators and accelerometers sensed the shock loads. The tests provided data for loads up to 10 g, and the results were within predicted, acceptable performance ranges.
