This paper discusses the problem of impact time control of an interceptor against a stationary target. A nonlinear guidance law is proposed with the interceptor heading angle variation as a function of the range to target. Closed-form expressions for the design parameters are derived for an exact analysis of the impact time. A feedback form of the guidance law is presented for addressing realistic...
In this paper, we propose a novel control structure that can achieve fast, safe and precise landing of a VTOL (vertical takeoff and landing) UAV onto a vertically oscillating landing pad. The control structure consists of three modules to achieve these goals: a motion estimation module, a trajectory generation module and a tracking control module. In the tracking control module, an ARC (Adaptive Robust...
When trying to estimate the location of a non-cooperative non-coherent emitter using intercepted signal measurements from a single airborne platform, the Doppler-based techniques, such as the Frequency of Arrival (FOA) is not applicable. In this paper, we propose a single platform long baseline interferometry (LBI) based emitter location estimator which achieves optimal estimation accuracy on average...
