During the Shipboard Integration of Sensor and Weapons Systems SISWS Technology Demonstration Project TDP, an algorithm was developed to automatically generate the optimal chaff solution as a function of missile initial range and velocity, wind velocity, and engagement geometry. The chaff solution algorithm was developed using customized score functions and simple models. The SISWS chaff seduction algorithm was improved by taking a more physical approach in the selection of chaff solutions, including a monopulse antenna model. The document starts with the scenario being modeled, followed by models for chaff, intersect ratio, monopulse seeker, and probability of soft-kill.
