This paper studies the feasibility of using China Mobile Multimedia Broadcasting (CMMB) signal for passive radar detection. The research focuses on the analysis of CMMB signal properties which include signal structure, spectrum analysis, target resolution, ambiguity function and reduction of side lobes. Since CMMB signal has wide bandwidth and high power in its coverage area, it has great advantages...
This paper deals with the problem of waveform design for through-the-wall radar with the presence of signal-dependent interference embedded in white Gaussian noise. Based on the target matched illumination theory, we present a linear combination method (LCM) to design the transmitted waveform for target detection. The LCM divides the waveform design problem into two independent optimization problems,...
This paper presents a study to demonstrate the feasibility of using digital video broadcasting-satellite (DVB-S) signal for passive radar. The study concentrates on the analysis of DVB-S signal properties, mainly including its spectrum, resolution capability, ambiguity function, and analysis of direct path signal-to-noise ratio (SNR). Since DVB-S signal has a higher range resolution due to its wide...
This paper investigates the passive radar detection system which exploits advanced broadcasting system-satellite (ABS-S) as opportunity illuminator. Firstly, the signal model is established and our ABS-S passive radar system architecture is presented. Then a low complexity and efficient cancellation method named a batch version of sequential cancellation algorithm (SCA-B) is proposed in signal processing...
Passive radars using illuminators of opportunity have attracted much attention in recent years. This paper presents a study to demonstrate the feasibility of using Advanced Broadcasting System-Satellite (ABS-S) signals for passive radar. The study includes system link budget, the design and implementation of an ABS-S based passive radar demonstrator, and the field measurements. The measurement results...
Target detecting and dynamic coverage are fundamental tasks in mobile robotics and represent two important features of mobile robots: mobility and perceptivity. This paper establishes the constrained motion model and sensor model of a mobile robot to represent these two features and defines the k -step reachable region to describe the states that the robot may reach. We show that the calculation of...
