The Influence and Elimination of Algorithm's Initial Value in Passive Location
Fu Zhong, Shaorong Li, Liao Ping · 2006
The influence of algorithm initial value on results in bearing-only passive location is described with geometry method. Via adding the phase difference as a new observation vector, a way to avoid this influence is proposed. And the nonlinear problem is transformed to linear problem. Simulations show that this way can improve the initial value's influence, and the relative error of distance is less than 2%.
