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.
Claims20
A system for identifying a pulsed radiation source, said system comprising:
- an imaging sensor having a frame rate that is asynchronous with a pulse repetition frequency (PRF) of the pulsed radiation source;
- and
- a processing unit in communication with said imaging sensor, and configured to:
- process a sequence of image data of a scene captured by said imaging sensor to determine whether radiation of the pulsed radiation source is detected;
- determine a PRF code of the pulsed radiation source from possible multiple different PRF codes based on the processed sequence of image data;
- and
- notify a user of the PRF code or information associated with the PRF code.
A method for identifying a pulsed radiation source, said method comprising:
- processing a sequence of image data of a scene to determine whether radiation of the pulsed radiation source is detected, the sequence of image data obtained using an imaging sensor having a frame rate that is asynchronous with a pulse repetition frequency (PRF) of the pulsed radiation source;
- determining a PRF code of the pulsed radiation source from multiple possible different PRF codes based on the processed sequence of image data;
- and
- presenting the determined PRF code or information associated with the PRF code to a user.
