• ### Three-Dimensional Tracking of an Aircraft Using Two-Dimensional Radars

Publication Year: 2018, Page(s):585 - 600
| | PDF (1547 KB)

Accurate three-dimensional (3-D) position and velocity estimates of an aircraft are important for air traffic control (ATC) systems. An ATC 2-D radar measures the slant range and azimuth of an aircraft. Thus, a single measurement from a 2-D radar is not sufficient to calculate the 3-D position of an aircraft. Previous researchers have used the multiple-model-based height-parametrized (HP) extended... View full abstract»

• ### Zero-Effort-Miss Shaping Guidance Laws

Publication Year: 2018, Page(s):693 - 705
| | PDF (2689 KB)

This paper suggests a new approach in designing homing guidance laws to enable direct shaping of the pattern of zero-effort-miss (ZEM) as desired. The proposed approach uses the concept of weighted ZEM and its specific desired error dynamics: the former is to provide an additional degree of freedom in shaping actual ZEM and the latter is to guarantee a finite-time convergence. Utilization of these... View full abstract»
