Further, it is shown that GRA, along with TDA, may eliminate the problem of radar blindness.In frequency-modulated continuous-wave (FMCW) radar interference suppression based on signal reconstruction, the pruned exact linear time (PELT) algorithm is used to detect the time positions of the interference. This article analyses automotive radar interference and proposes several new approaches, which combine industrial and academic expertise, toward the path of interference-free autonomous driving. Autonomous driving relies on a variety of sensors, especially on radars, which have unique robustness under heavy rain/fog/snow and poor light conditions. We model the weather signal as group sparse in the time–frequency domain; in parallel, we model the WTC signal as having a sparse time derivative.

The method is validated experimentally using measurements of an OFDM radar setup at 76 GHz and a state-of-the-art FMCW radar as an interferer.The application of radar sensors for driver assistance systems and autonomous driving leads to an increasing probability of radar interferences. To address interaction capabilities between vehicles and environment, we focus on radar processing methods with signals that allow for communication functionality.ce caused by other automotive radars. Due to the uncertain penalty factor of the PELT algorithm, the exactness of the position detection is reduced; thus, the suppression performance is degraded. In addition, noise enhancement effects can be effectively mitigated through the proposed cancellation technique.An essential prerequisite for radars in automotive applications, safety systems, future autonomous driving, and industry applications is the reliable operation even under difficult conditions such as interference from other radars.

Multiple-input, multiple-output (MIMO) radar technology has been receiving considerable attention from automotive radar manufacturers because it can achieve a high angular resolution with relatively small numbers of antennas. In this paper, we propose a graph-based resource allocation (GRA) scheme to assign resources to the running SDV pool. Moreover, oscillator imperfections and relative velocity effects induce inter-carrier interference (ICI) owing to frequency offset, leading to degradation of target detection. In this paper, time-frequency resources are divided into several orthogonal logical channels according to the time-frequency division (TFD) scheme.
The latter happens from a distance called Target Self-Masking Distance (TSMD).e automated transport system is researched and designed, consisting of dual mode vehicles which can be driven automatically and manually to allow maximum flexibility.
