Research on control strategy of four rotorcraft tracking ground moving target
In order to enable the four rotorcraft to track the ground moving target, the spatial position control strategy of four rotorcraft is studied. Firstly, the attitude PID control of the four rotorcraft is improved and the appropriate parameters are set ...

Detecting Moving Target on Ground Based on Its Shadow by Using VideoSAR
Video synthetic aperture radar (VideoSAR) can detect and identify a moving target based on its shadow. A slowly moving target has a shadow with distinct features, but it cannot be detected by state-of-the-art difference-based algorithms because of minor ...

An Accurate Imaging and Doppler Chirp Rate Estimation Algorithm for Airborne CSSAR-GMTI Systems
Airborne circular stripmap synthetic aperture radar (CSSAR)-ground moving target indication (GMTI) systems are attractive tools for air-to-ground surveillance and monitoring, because of their advantages of short revisit time and large coverage.

Moving ground target isolation by a UAV using predicted observations [PDF]
An interesting variant of the cops and robbers pursuit-evasion problem is presented. The motivation for the problem comes from the need to monitor a network of roads leading to a protected area. In this paper, an unmanned aerial vehicle (UAV) is searching for a slower moving ground vehicle on a road network that has been out-fitted with unattended ...

Group object structure and state estimation with evolving networks and Monte Carlo methods. [PDF]
This paper proposes a technique for motion estimation of groups of targets based on evolving graph networks. The main novelty over alternative group tracking techniques stems from learning the network structure for the groups.

Radar imaging of ground moving targets
We analyze the effect of target motion on synthetic aperture radar images and discuss how a multi-aperture radar can detect, focus and relocate moving targets in clutter. AN/APY-6 radar data is used for analyzing the radar imaging of ground moving targets.

GMT-WGAN: An Adversarial Sample Expansion Method for Ground Moving Targets Classification
In the field of target classification, detecting a ground moving target that is easily covered in clutter has been a challenge. In addition, traditional feature extraction techniques and classification methods usually rely on strong subjective factors ...
