This chapter presents coordinated standoff tracking strategies to follow unknown moving ground vehicles using multiple UAVs equipped with an on-board ground moving target indicator sensor. Various recent algorithms on standoff tracking such as vector field guidance, nonlinear model predictive control, and group target tracking are introduced along with relevant target estimation and sensor fusion techniques required to obtain target's movement accurately. To show the feasibility and benefits of the presented algorithms, numerical simulation results are presented using car trajectory data obtained from a realistic traffic simulator. Furthermore, advantages and disadvantages/limitations of each method are discussed both quantitatively and qualitatively. Keywords: nonlinear model predictive control; road-constrained filtering; sensor fusion; standoff tracking guidance; UAVs; vector field guidance |
