Abstract : This report documents the development and incorporation of a stochastic Optical Contrast Seeker Model into the existent Monte Carlo point target terminal homing 6-DOF simulation program. In addition the basic pitch and yaw seeker platform dynamics, parameter target size, seeker breaklock, seeker blind range, transport log, and helicopter induced launch transients are included. Platform imperfections such as mass unbalance and rate gyro drifts were modeled. Each data point generated by the simulation is obtained from the statistical reduction of approximately 25 individual runs (depending on number of breaklocks), each of which has new random starting and within run variations. The runs are reduced by parametric or nonparametric means, depending on the normality of the miss distance points, to yield the miss bias (mean) and the circular error probability (CEP).
