Abstract
A sensor is used to detect and track a plurality of objects by using a separate track window for each object. Such sensors may be electro optical or infrared. Each object of interest (potential target) in the sensor FOV has a unique track window assigned. This allows independent control of video frame summing for each object to maintain a constant (optimized) signal to noise ratio (SNR) over an extremely large signal dynamic range and reduces track jitter by the simultaneous tracking of multiple objects.
