## Discrete‐Time Three‐Dimensional Tracking Filters

ByK. V. Ramachandra

In this chapter, three‐dimensional tracking filters are discussed for estimating the position, velocity, and also acceleration of an aircraft when the range r, bearing θ, and elevation ϕ of the target are measured at uniform sampling intervals of time T seconds through random noise by a three‐dimensional radar sensor. The tracking operation is assumed to be performed in the cartesian coordinate system. The coupling between the quantities measured by the radar (r, θ , φ ) $\theta , \varphi )$ and the cartesian coordinate system selected for tracking operation is explicitly considered in the development of the three dimensional models.
