Abstract
An open loop proximity detector is contemplated which receives a Doppler frequency when a target is first detected, and predicts a specific fuzing Doppler frequency. The detector continues to transmit and receive electromagnetic waves and sends a detonating signal to the fuze when the predicted fuzing Doppler frequency is received by the detector. The Doppler frequency of the first, or front surface in a forward moving direction of the target is received and is used to detonate the fuze. Thus the ideal surface of the target, the front surface, detonates the fuze and Doppler frequencies from other surfaces of the target are not allowed to interfere with the detonating process.
