Abstract
To achieve the rapid calculation of the laser guided bomb's total capture area, based on the principles of capture target of laser seeker, taking the target point as center, the instant capture area model was established and the shape of instant capture area and its deciding factor were analyzed. On this basis, the calculation method of total capture area of laser guided bomb was proposed. Secondly, under the assumption of flight path angle keeping constant, the total capture area's theoretical expressions of guided bomb with gimbaled seeker or strapdown seeker were put forward. Finally, the results of total capture area of laser guided bomb guided by proportional navigation guidance and trajectory shaping guidance calculated through theoretical expression and computer simulation were contrasted. The results show that the expression's result matches the simulation and the theoretical expression can be used on fast calculation of laser guided bomb's total capture area.
