Abstract:
1. A system, comprising: a laser designator configured to continuously designate a target with a pulsed laser spot; a sensor and associated processor configured to receive a reflection of the laser spot, convert the received energy to plurality of signals, processing the signals for detecting at least one true reflected signal, wherein said detection of said at least one true reflected signal includes determining at least one candidate true signal using non-coherent integration, and wherein said sensor and associated processor are configured to process at least one of the true reflected signals for generating target related action, and to detect said at least one true reflected signal notwithstanding an inherent low Signal/Noise ratio of below 4 of received signals from among said plurality of signals due to at least one factor selected from a group that includes low pulse power of the laser designator and distance to target; and wherein a sampling clock of the received signal in the sensor and a generation clock of the pulses in the laser designator are not synchronized.
