The Bearing-Only Target Motion Analysis (BOTMA) problem is to estimate the position and velocity of a target using bearing measurements. In this paper, we assume that the observer can access the inequality constraints imposed on target's speed, range, or target's course. For example, one constraint on a target's range is that it is upper bounded by the(More)
The Doppler-Bearing Target Motion Analysis (DBTMA) problem arises in various military applications related to target tracking. The DBTMA problem is to estimate the position and velocity of a target using both frequency and bearing measurements. As the method to increase the estimation accuracy in the DBTMA problem, this paper introduces observer motion(More)
