METHOD FOR DEFINING SPEED OF AMMUNITION APPROACHING TARGET Russian patent published in 2013 - IPC F42C13/02 G01S17/58 

FIELD: weapons and ammunition.

SUBSTANCE: method involves determination by measured value the time interval between target identification at two different specified distances and is based on detecting the object via space exploration by light pulses and recording of reflected radiation with sequential analysis. Radiation of sounding light pulses is done by one transmitter and recoding of reflected radiation - by one receiver located on ammunition, note that there radiated are the specified series of light pulses within specified time interval, at that the signal of target identification is formed providing the recording of reflected signals of all radiated light pulses of current series and recording of final reflected series signal in test time interval.

EFFECT: provision of possibility to determine the speed of ammunition approaching the target not depending upon the speed and type of ammunition with the possibility of protection from small-size interferences influence, provision of possibility to minimise dimensional and weight characteristics and energy consumption of the device.
