Two new target models have been developed by expressing the target acceleration in circular coordinates and treating the angle as a random process (CFC) and treating both the angle and the magnitude as random processes (CFV). An extended Kalman filter has been developed for each target model, and noisy measurements generated for a deterministic missile/target engagement have been processed. To reduce the amount of work required to establish the feasibility of these filters, only two-dimensional results have been developed. Preliminary results indicate that the CFV produces better tracking results than the CFC, which under certain conditions, is comparable with the filter containing the Gauss-Markov target model. This is true even when there is a mismatch between the actual noise level and noise level assumed in the filter. As a consequence, the circular target model filter with variable target acceleration merits further investigation.
