A comparative study of pursuit and proportional navigation laws to be used in emitter homing simulations is made for several types of flight vehicles. The framework for this study, although relatively simple, includes the essential features of the two control laws, such as the aero/inertial characteristics of the airframe and the important parameters of the autopilot. Both deterministic and stochastic error models of wind, sensor, gyro, and accelerometer are considered. The main conclusions of the study are that gyro bias and sensor noise are dominant for proportional, while wind and sensor bias are most important for pursuit. Proportional was found to be more effective than pursuit, but implementation of proportional with a strapdown sensor may require a more accurate gyro than usually required by an autopilot. (Author)
