Microwave signal at 24,000 Mc is aimed down barrel of howitzer by sheet aluminum reflector that is replaced abet each firing. Variations in reflection coefficient of ferrite device on projectile nose modulate reflected micro-wave signal from moving projectile, at frequency dependent on acceleration. Circuit shows encapsulated transducer mounted on nose. Capacitance gage produces frequency shift of 70-kc subcarrier that is proportional to acceleration, for driving ferrite-core modulator through amplifier stage.-W. M. Kendrick and L. A. Peters, Projectile Telemetry with Microwaves, Electronics, 33;38, p 68-71.
