Description

[Brief explanation of the drawing]

FIG. 1 is an overall configuration diagram of an embodiment of a distance measuring device according to this invention, FIG. 2 is an explanatory diagram of its operation, and FIG. 3 is a diagram showing the principle of a conventional distance measuring device. In the figure, 1 is a tracking device, 2 is a sequence controller, 3 is a timer, 4 is an accelerometer, 5 is a connection circuit, 6 is an integrator, 7 is a double integrator, and 8 is an arithmetic unit. Note that the same reference numerals in the figures indicate the same or corresponding parts.

Claims (1)

[Scope of utility model registration request] A tracking device that tracks a target in a flying object that has a period of flight at a constant altitude over land or sea, an integrator that integrates the tracking angular velocity signal output from the tracking device, and an input of the tracking angular velocity signal to the integrator. a sequence controller that outputs a ranging command signal from the tracking status signal output from the tracking device, an accelerometer that detects the acceleration in the direction of movement of the flying object, and an acceleration signal from this accelerometer. A double integrator that integrates twice, a connection circuit that connects and disconnects the input of the acceleration signal to the double integrator,
A timer that generates a connect/disconnect command signal for the connected circuit based on the distance measurement command signal mentioned above, and a target angle change signal output from the integrator and a target movement distance signal output from the double integrator are used to determine the target by predetermined calculations. A distance measuring device equipped with a distance calculator that generates a distance signal.
