“…Another way to design the cooperation methods is to use modulation techniques. Some researchers proposed to use sidelobe amplitude shift keying (ASK) for the JRC systems, however these methods are not investigated so far under fading channels [123], [124]. Obviously, the fading environment actually exists in wireless channels due to multipath propagation.…”

Joint radar and communication (JRC) technology has become important for civil and military applications for decades. This paper introduces the concepts, characteristics and advantages of JRC technology, presenting the typical applications that have benefited from JRC technology currently and in the future. This paper explores the state-of-the-art of JRC in the levels of coexistence, cooperation, co-design and collaboration. Compared to previous surveys, this paper reviews the entire trends that drive the development of radar sensing and wireless communication using JRC. Specifically, we explore an open research issue on radar and communication operating with mutual benefits based on collaboration, which represents the fourth stage of JRC evolution. This paper provides useful perspectives for future researches of JRC technology.

“…, where G(θ) is the desired transmit beam-pattern, Θ is the spatial sector the radar keeps under surveillance, Θ is the sidelobe region for communication, is a positive number of users choice for controlling the sidelobe levels, and ∆ k is the k-th sidelobe level toward the communication direction θ c . Several other variations of the sidelobe modulating approach are discussed in [58], [59].…”

Increased amounts of bandwidth are required to guarantee both high-quality/high-rate wireless services (4G and 5G) and reliable sensing capabilities such as automotive radar, air traffic control, earth geophysical monitoring and security applications. Therefore, co-existence between radar and communication systems using overlapping bandwidths has been a primary investigation field in recent years. Various signal processing techniques such as interference mitigation, pre-coding or spatial separation, and waveform design allow both radar and communications to share the spectrum. This article reviews recent work on co-existence between radar and communication systems, including signal models, waveform design and signal processing techniques. Our goal is to survey contributions in this area in order to provide a primary starting point for new researchers interested in these problems.

A dual-function radar-communication system is a technology equipped with a joint platform that enables performing a radar function (primary function) and a communication function (secondary function) simultaneously. This duality has become increasingly necessary, since it alleviates congestion and ease competition over frequency spectrum. In this paper, we put forward a technique for information embedding, specifically to multiple-input multiple-output (MIMO) radar employing frequency-hopping chirp (FHC) waveforms. We use FHC codes to implement the primary function (i.e., MIMO radar operation), while embedding communication symbol, for example, phase shift keying (PSK), in each FHC code for secondary function (i.e., communication operation). We show that the communication operation does not interfere with the MIMO radar function. In addition, standard ratio testing is used at the communication receiver to detect the embedded PSK symbols. Furthermore, the waveform designed has the superiorities of high range resolution, constant time domain and almost constant frequencydomain modulus, large time-bandwidth product, and low time-delay and frequency-shift correlation peaks. Numerical results show that: 1) data rates can be accurately detected, and thus, several Mbps are achieved in the system; 2) the SER performance characteristics are significantly improved; 3) the orthogonal frequency-hopping chirp waveforms achieve better range and Doppler resolution with reduced sidelobes levels compared to that of conventional frequency hopping waveforms. INTRODUCTIONThe concept of coexistence of radar and communications on a single platform has been proposed as a solution to the radio frequency spectrum congestion and also attracted a lot of attention [1,2]. Since there has been a huge demand from communication operators, the competition between the radar and communication in terms of frequency spectrum could be eased by allowing both systems to share the same resources and operate simultaneously from a single platform [3][4][5][6][7][8][9][10][11][12][13][14][15][16]. This implies that we can achieve an efficient utilization of the limited frequency spectrum resources. Recently, the concept of dual-function radar-communication (DFRC) has been proposed [16]. The main idea about this concept is to utilize identical signals and the same antenna array for both radar (primary function) and communication (secondary function) operations simultaneously. A number of papers [16][17][18][19][20][21][22][23][24][25] have investigated the capabilities of dual-function radar-communication (DFRC) system. DFRC systems utilize the full potential of radar resources, for instance, high quality hardware and high transmit power. Embedding information into the radiation of single-input multiple-output (SIMO) radar can be done by employing the following: 1) waveform diversity, 2) sidelobe control, and 3) time modulated array.Lately, information embedding into the radiation of multiple-input multiple-output (MIMO) radar has been reported in [23][24][...
