SELF-HOMING DEVICE Russian patent published in 2010 - IPC F41G7/22 

FIELD: physics, navigation.

SUBSTANCE: invention relates to navigation equipment and is primarily meant for solving the problem of self-homing through constant-bearing approach of short-term interacting small aircraft. The device has an antenna, a radar set, a timer and a control device. There are two evaluators, an electronic switch, two memory units, a logic device and a control device. The antenna is connected to the first input of the radar set whose output is connected to the first inputs of the first evaluator and the first memory unit. The output of the first evaluator is connected to the first input of the second evaluator and to series-connected electronic switch and second memory unit, the output of which is connected to the second input of the first evaluator, whose output is connected through the first input of the logic device to the input of the control device. A standard one signal is transmitted to the second input of the logic device. The output of the control device is the output of the entire device. The radar set, whose second input is connected to the output of the timer, can be a range finder of a Doppler frequency measuring device.

EFFECT: simple design and broadening options for controlling kinematic motion through constant-bearing approach.
