In view of the difficulty of tracking and testing artillery terminal sensitive submunition, by using the photoelectric theodolite, radar, command and control equipments to build the test system, by modeling and simulation design optimization of the layout of the photoelectric theodolite test sub system, design a combination of multiple tracking modes of the composite tracking model, The test capability of the test system for the gun sensitive bullets is improved. Using this technique to test 18 rounds of certain type of artillery terminal sensitive submunition, with an image test success rate of 88.9% and a ballistic test success rate of 77.8%, the test results show that the technique can be applied to the ballistic parameter test of the target range of the gun and has important reference significance for the target tracking test of the gun separation category.
