@HLCPTR,
Aware of LIDAR but not the same system. RODAR is integral to the main rotor therefore requires nothing to be mounted externally on the fuselage. If EO capability could be added to the rotor tips then not even a gimbal mounted EO sensor would be required affording a clean fuselage and the inherent increase in aerodynamic and thus fuel efficiency. Development stagnation could be nothing more than sorting out payment to the multitude of current patent holders. It's always about money in the end, even something that could definitely save lives...
