Abstract: Modern warfare includes extensive use of laser-based devices and laser-guided weapons. This large-scale use of laser-based systems means that all weapon platforms are vulnerable to attack by laser-guided munitions (LGM). Such a situation emphasises the importance of timely detection and recognition of laser threats. This necessitates that friendly platforms are equipped with a suitable laser-warning sensor that will provide timely information about the incoming laser threat with a high level of angle-of-arrival accuracy so that a suitable countermeasure action can be initiated against it. This paper (Part II of a two-part series of papers) discusses the design of the electronic processing module of a laser-warning system (LWS) having an opto-electronic front end designed using an array of discrete photo-diodes (the design aspects of, and test results for, the opto-electronic front end has been discussed in the first part). This is followed by a brief discussion on its simulated evaluation process and the test results for the determination of the angle of arrival and PRF of a laser threat.
