JET MISSILE RANGE FINDER Russian patent published in 2013 - IPC F42C13/02 

FIELD: weapons and ammunition.

SUBSTANCE: jet missile range finer comprises electronic unit and transceiving channels. Optical axes of said source and receiver that make transceiving channel with their optical axes are directed at the angle to missile lengthwise axis and shifted relative to each other, primarily. Note here that transceiving channels are arranged around missile lengthwise axis. Preferably in plane perpendicular to its lengthwise axis. The angle in radial direction between axes of radiators makes light beams of radiators not intersecting. Spacing between adjacent radiation channels at required target detection range equals or approximates to minimum target size. Optical radiator and photo receiver are connected with electronic unit to perform time-pulse analysis of range to target.

EFFECT: higher probability of target detection and guidance, better protection against optical and small size interferences, decreased weight and overall dimensions.
