GROUND OBJECT DETECTION DEVICE Russian patent published in 2011 - IPC F41G3/00 

FIELD: weapons and ammunition.

SUBSTANCE: device includes optic system the output of which is connected to input of optic signal divider. Outputs of divider are connected to inputs of two-channel photo-receiving device. The first output of photo-receiving device is connected to the first inertia detector and to the first input of the first adder, and the second output is connected through adjustable amplifier to input of the second inertia detector and to the second input of the first adder. Outputs of the first and the second inertia detectors are connected to the first and the second inputs respectively of the second adder and to the first and the second inputs of subtracting device. Output of subtracting device is connected to control input of adjustable amplifier. Output of the first adder is connected through voltage divider to direct input of the first comparator. Output of the second adder is connected through maximum signal extraction device to inverting input of the first comparator the additional input of which is connected to altimeter. The first output of two-channel photo-receiving device is connected to input of amplitude detector and to the first input of the second comparator. Output of the first comparator is connected to the enable input of timer count and to the enable input of amplitude detector. Output of amplitude detector is connected to the second input of the second comparator, and output of timer is connected to enable input of the second comparator.

EFFECT: higher detection accuracy of ground objects of the specified sizes.
