The extraction algorithm of target characteristics resonance set at the high-frequency band plays a significant role in defense applications like early warning. The paper proposes a new method to extract the characteristic resonance set of radar targets in the resonance frequency region using an autoregressive moving average model optimized by root...
Multi-target UXO areas are often unavoidable during field exploration. However, most geoelectric models focus only on single targets and are not always reliable for “detection” and ”identification” of multi-density UXO. In this paper, we firstly compare the numerical simulation results with the analytical solution to verify the correctness of the 3...
Radar target characteristics need to be accurately extracted to enhance the role of high-frequency (HF) radar target recognition technology in modern radar, sea and air monitoring, and other applications. The pole characteristics of radar targets have become a mainstream research focus because of their inherent advantages for target recognition. Ho...
This paper establishes a distributed multistatic sky-wave over-the-horizon radar (DMOTHR) model and proposes a semidefinite relaxation positioning (SDP) algorithm to locate marine ship targets. In the DMOTHR, it is difficult to locate the target due to the complexity of the signal path propagation. Therefore, this paper uses the ionosphere as the r...
In this letter, a three-dimensional (3D) joint estimation algorithm which is the variable-step hill-climbing algorithm based on two-step weighted least squares (VHC-2WLS) is proposed. The VHC-2WLS combines bistatic range (BR), time difference of arrival (TDOA) and Doppler shift (DS) to improve the estimation accuracy of the position and velocity of...
With the rapid development of the Internet of Things (IoT), autonomous vehicles have been receiving more and more attention because they own many advantages compared with traditional vehicles. A robust and accurate vehicle localization system is critical to the safety and the efficiency of autonomous vehicles. The global positioning system (GPS) ha...

... It enhances situational awareness and contributes to safer navigation. A robust and accurate vehicle localization system consisting of a bistatic passive radar is proposed, which exhibits better performance than the existing sparse signal representation-based algorithms, and performs well in the vehicle localization system [18]. Cantarini et al. [19] introduces a prototype of an emergency vehicle detection system based on audio and video sensors. ...
