    摘要： This invention provides a fuze which includes metering means for deriving a firing signal from the frequency-time characteristic of electrical analogue signals derived from the vibrations emanating from a moving vehicle. The firing signal may be derived by integrating or differentiating the characteristic or by measuring the instantaneous frequency of the analogue signals.

    摘要： A target engagement system uses target motion analysis to determine a target engagement decision for ground targets, such as vehicles. The input to the engagement system is the target azimuth as a function of time. A detect algorithm issues and records a detect azimuth when confirmation is made that a valid target is being tracked and legitimate azimuth information is being provided. The engagement algorithm then begins and records the time intervals it takes for the target to cross two sectors, each covering 20.degree. and separate by 10.degree.. Thus, first time interval is measured from detect azimuth to 20.degree. after detect azimuth, and the second time interval is measured from 30.degree. after detect azimuth to 50.degree. after detect azimuth. When the first and second time intervals have been recorded, the ratio of the first time interval to the second time interval is calculated. If this ratio is greater than 2.0, then the target is estimated to be within range and is subsequently attacked. Otherwise, the target is greater than the range and no action is taken.

    摘要： A pop-up mine, anchored to the bottom and remaining under the surface of a body of water for destroying ASW and sonar dunking helicopters. The mine case includes an outer skin comprising fragment projectiles bonded to an explosive sheet. Deployed by a submarine, an anchor separates and sinks to the bottom, paying out cable to leave the mine close to the surface. A hydrophone, discriminating for detecting helicopters, activates a cable cutter and a rocket motor. The mine case pops to the surface, is lifted by the rocket to a predetermined altitude, and explodes to disperse the metal fragments, thus disabling the helicopter.
