Considering a simultaneously transmitting and reflecting reconfigurable intelligent surfaces (STAR-RIS)-aided dual-functional radar-communications (DFRC) system, this paper proposes a symbol-level precoding-based scheme for enhancing the physical layer (PHY) security of the confidential information transmission and performing target sensing simultaneously. Specifically, the STAR-RIS-aided DFRC system design objective is to maximize the average received radar sensing power subject to the quality-of-service constraints for multiple communication users, the security constraint for multiple potential eavesdroppers, as well as various practical waveform design restrictions. However, the formulated problem is challenging to handle due to its nonconvexity. To address these issues, we propose a distance-majorization induced low-complexity algorithm to obtain an efficient solution. Simulation results confirm the effectiveness of the STAR-RIS in improving the DFRC performance.

In this paper, we explore the properties of various mathematical structures for use in radar applications, namely Orthogonal Sudoku arrays and Costas Cubes. The overarching theme is for the paper to serve as a foray into further explorations of these structures in more radar specific areas (e.g. noise radar). We, therefore, provide a brief description of each of these structures using mathematical theory before pivoting into computational results and a radar specific application in antenna array patterns. Afterwards, the key points of this exploration and further application of these structures in radar is then discussed.

With the advancing sensor (receiver-processor) technology, Time Difference of Arrival (TDOA) based systems have become attractive for estimating the direction of a transient or pulsed signal. Compared to traditional phase or amplitude comparison-based direction finding (DF) systems, distributed TDOA systems have several advantages. These include the absence of uncertainty problems, direction of arrival (DOA) estimation independent of sensor and signal characteristics, mobility, and the dynamic array manifold structure. On the other hand, in distributed TDOA systems, a synchronization problem arises among clocks since each node has its own local clock. This article introduces a deep neural network (DNN) structure capable of estimating the direction of a signal in the presence of time offset. Experimental (simulation) results demonstrate that the proposed method outperforms classical approaches.
