Abstract: System for detecting objects protruding from the surface of a body of water in a marine environment under low illumination conditions, the system comprising a gated light source, generating light pulses toward the body of water illuminating substantially an entire field of view, a gated camera, sensitive at least to wavelengths of the light generated by the gated light source, the gated camera receiving light reflected from at least one object, within the field of view, protruding from the surface of the body of water and acquiring a gated image of the reflected light, and a processor coupled with the gated light source and with the gated camera, the processor gating the gated camera to be set 'OFF' for at least the duration of time it takes the gated light source to produce a light pulse in its substantial entirety in addition to the time it takes the end of the light pulse to complete traversing a determined distance from the system and back to the gated camera, the processor further setting, for each pulse, the gated camera to be 'ON' for an 'ON' time duration until the light pulse, reflecting back from the object, is received by the gated camera.
