Described herein is a sighting mechanism that includes a system (10) for modifying an optical sight which does not suffer from disadvantages associated with poor visibility. The system (10) includes a source of continuous wave (CW) radiation (16) that provides CW radiation to an antenna (22) for illuminating a field of view. The antenna (22) also collects reflections from objects within the field of view for processing. If only moving objects within the field of view are of interest, reflections from stationary objects that are at the same frequency as the illuminating radiation can be discarded. For moving objects, the reflections are modulated in accordance with the movement of the object and have a frequency that is proportional to their radial velocity. The modulated reflections can be interpreted rather well by the human brain and can be relayed directly to the user through ear phones or other similar devices.
