  • Target detection device
    Patent number: 4236157
    Abstract: A target detection device which functions a warhead at a predetermined het above the surface of the earth. A frequency modulated, pseudo-noise coded signal reflects from the surface of the earth to provide Doppler signals to a dual gate Doppler amplifier system. The voltage outputs of the two gates are compared; and a signal is sent to a threshold circuit to ascertain when a predetermined relationship exists between the two voltage outputs to decide when the target detection device is at a predetermined height, at which time a trigger signal actuates a time delay circuit using the Doppler frequency to generate a time delay that is dependent upon the vertical velocity of the target detection device. After the time delay, a signal is sent to a firing circuit which produces a firing pulse to function the warhead.
