Abstract: The presently disclosed subject matter includes a laser system and a respective method of detecting a signal reflected from a target illuminated by a modulated CW light source configured to generate a modulated laser signal at a predefined modulation frequency. A signal comprising true laser signal portions reflected from said target, and noise is received; the signal is filtered for selecting laser signal portions at a modulation frequency band; and the true signal portions in the signal are detected, if the energy at the modulation frequency band is greater than a given threshold.

Abstract: The presently disclosed subject matter includes a method and system for enabling detection of signal reflection from a target designated by a pulse laser spot generated by a low-power laser designator. A signal comprising true signal portions reflected from said target and noise is received and sampled and a first value or a second value is assigned to each sample. The assigned (ith) values in K pulse rate intervals are summed to obtain respective summed values. One or more candidate clusters are identified from among the summed values and a final candidate cluster is selected from among said one or more candidate clusters. The final candidate cluster is located with respective samples of an incoming pulse rate interval, thereby detecting an area within said signal which comprises the true signal portions.

Abstract: A method for tracking an object that is embedded within images of a scene, including: in a sensor unit, generating, storing and transmitting over a communication link a succession of images of a scene. In a remote control unit, receiving the images, receiving a command for selecting an object of interest in a given image and determining object data associated with the object and transmitting the object data to the sensor unit. In the sensor unit, identifying the given image and the object of interest using the object data, and tracking the object in other images. If the object cannot be located in the latest image of the stored succession of images, using information of images in which the object was located to predict estimated real-time location thereof and generating direction commands to the movable sensor for generating realtime images of the scene and locking on the object.

Abstract: A system that includes a laser designator configured to continuously designate a target with a pulsed laser spot. The system includes a sensor and associated processing system configured to receive a reflection of the laser spot, convert the received energy to plurality of signals, processing the signals for detecting true reflected signals and process the true reflected signals for generating target related action. The sensor and associated processor are configured to detect the true signals notwithstanding an inherent low Signal/Noise ratio of below 4 of the received signals from due to low pulse power of the laser designator and distance to target.
