Reconnaissance mission has a wide application in both civil and military fields, which provides intelligence basis for the following decision-making to accomplish certain goals. Due numerous advantages of UAV swarms such as strong flexibility, high efficiency, low cost, conducting reconnaissance missions by become trend future. However, path planning problem is key challenge aspect model construction, algorithm, selection computational complexity, especially when complicated. In this paper,...
In this paper, the angle-of-arrival (AOA) measurements are adapted to locate a target using UAV swarms equipped with passive receivers. The measurement noise is considered be target-to-receiver distance dependent. Cramer-Rao low bound (CRLB) of AOA localization calculated, and optimal deployments explored through changing angular separations distances. Then, distributed collaborative autonomous generation (DCAG) method proposed based on deep neural network (NN). off-line training on-line...
Source localization based on the hybrid time-difference-of-arrival (TDOA) and frequency-difference-of-arrival (FDOA) measurements from distributed sensors is an essential problem in wireless sensor networks (WSNs).

The Cramer-Rao low bound(CRLB) calculated incoming measurements. Then method for optimizing UAVs trajectories based on CRLB proposed. Dryden applied and performance disturbance-TDOA analyzed in terms root mean square error (RMSE). Simulations confirm online optimization enables high accuracy show robust...
Finding a small subset of data whose linear combination spans other points, also called column selection problem (CSSP), is an important open in computer science with many applications vision and deep learning. There are some studies that solve CSSP polynomial time complexity w.r.t. the size original dataset. A simple efficient algorithm order, referred to as spectrum pursuit (SP), proposed pursuits spectral components dataset using available sample points. The non-greedy aims iteratively...
