This report describes the equations of motion required of a monitoring aircraft to track successfully a moving target emitter by sequential bearing only information. When the monitoring aircraft and the target both describe straight line constant velocity motion, unambiguous tracking cannot be carried out, unless a priori knowledge of at least one of the targets parameters of motion is available. However, this ambiguity is resolvable for most real situations, when the monitoring aircraft purposely describes nonlinear motion and the target is still assumed to have linear motion. If the formers motion is of a sufficiently high degree of nonlinearity, such as circular motion, no ambiguities whatsoever will occur in any tracking situation. Author
