Abstract
A system and method for identifying a pulsed radiation source may include an imaging sensor having a frame rate that is less than a pulse repetition frequency (PRF) of the pulsed radiation source. A processing unit may be in communication with the imaging sensor, and be configured to (i) process a sequence of image data of a scene captured by the imaging sensor to determine whether radiation of the pulsed radiation source is detected, (ii) determine a PRF code of the pulsed radiation source from possible multiple different PRF codes based on the processed sequence of image data, and (iii) notify a user of the PRF code or information associated with the PRF code.
