Abstract

Laser-guided munitions are weapons of great importance in the present day warfare scenario because of their precision and efficacy. Both weapon specific and generic test systems are commercially available to perform functionality checks on laser guided munitions. None of the designs reported in literature addresses the issues of universality of test systems and their ability to evaluate the device-under-test in actual battlefield scenario. This paper presents the design of an electro-optic device that offers significant improvement over the features of both commercial test systems as well as the designs reported in recent literature. The proposed design enables generation of user programmable laser signatures in terms of pulse repetition frequency (PRF) code, PRF code resolution and laser power density that allows testing in dynamic conditions not possible with the test systems in the state-of-the-art. The concept is hardware implemented and used to evaluate performance of a typical laser seeker. The seeker is tested for PRF code compatibility, immunity to false PRF codes, sensitivity, field-of-view and performance in dynamic conditions. The test results are also presented.
