Integrated radar-communication systems will play an important role in the future battlefield scenarios by decreasing the interference, volume, weight, and power consumption of equipment and promoting information fusion with an enhanced network. An active electronically scanned array radar system is ideal for such scenarios. However, a few studies have focused on the modeling and detection of communication signals for such integrated systems. In this paper, an array division strategy is developed, and a low-complexity signal detection scheme based on the generalized approximate message-passing (GAMP) algorithm is implemented. Furthermore, a quantization model is introduced into the output function of the GAMP algorithm. The method effectively provides communication signal detection with low-precision quantization and outperforms the linear minimum mean square error-based algorithm at the same precision levels. Overall, an energy-efficient radar-communication strategy is developed to promote the application of such systems in the future battlefield scenarios. INDEX TERMS Integrated radar-communication system, GAMP algorithm, low-precision quantization algorithm, energy efficient. I. INTRODUCTION In the future integrated battlefield of sea, land, air and space, military platforms such as tanks, airplanes, and ships will be loaded with diverse electronic devices to enhance their interoperability and probability of survival [1], [2]. Various problems, such as interference, volume, weight, and power consumption issues, linked to these electronic devices will become increasingly serious [3], [4]. An integrated radarcommunication system can largely alleviate or even solve the above problems by sharing hardware resources such as antennas and radio frequencies [5], [6]. Determining how to integrate radar and communication systems is crucial for improving the comprehensive performance of military platforms. The associate editor coordinating the review of this manuscript and approving it for publication was Qinghua Guo. Active electronically scanned array (AESA) radar has a flexible radio frequency (RF) beamforming capability and multifunction parallel execution capability [7]; therefore, it is suitable for the carrier platform in integrated radarcommunication systems. AESA radar was used to conduct communication experiments in [8] and [9], but there is little research on system design and modeling for simultaneously employed radar and communication functions. In fact, since the communication signal and the radar echo are received through the same antenna array, it is necessary to reasonably divide the array. On the one hand, the integrated radar-communication system must communicate with many objects in different directions to establish a complex communication network. On the other hand, the influence on radar detection performance due to the use of some antenna elements for communication should be minimized. Therefore, based on AESA radar, this paper designs a method

“…There are several design methodologies in the literature for generating beam-forming networks. There is an interesting study line from the traditional (or classical) networks such as the butler matrix [ 3 ], Blass [ 4 ], and Nolen [ 5 ] to the most recent feeding networks for reducing the number of active devices including the application of subarrays [ 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 ], overlapping techniques [ 14 , 15 , 16 , 17 , 18 ], interleaving schemes [ 19 ] and CORPS (coherently radiating periodic structures) networks [ 20 , 21 , 22 , 23 ].…”

This paper presents a new scheme of applying CORPS (coherently radiating periodic structures) for reducing the number of phase shifters in linear antenna arrays. This scheme can be seen as a combination of the properties of two techniques: CORPS and butler. The proposed system applies an interleaving of several blocks of 2 × 3 CORPS networks. This interleaving of two stages of 2 × 3 CORPS networks is made in a convenient way to provide the required progressive phase for beam-scanning and the level of amplitude excitations necessary for achieving the radiation characteristics of low SLL. Interesting results are provided based on experimental measurements and full-wave simulations to analyze and evaluate the performance of the feeding network based on CORPS and the reduction capability of the number of phase shifters in the antenna system. The proposed design methodology achieves a reduction capability of 66% in the number of phase shifters used in linear antenna arrays. This reduction in the complexity of the antenna system is reached maintaining a peak SLL of −22 dB with scanning ranges of until ±25°. A good design option is provided to simplify the complexity of the feeding network in antenna array applications.

The subarrays technology considers randomly grouped subarrays in linear and planar arrays for a reduced number of PS.…”

This paper illustrates the application of CORPS (coherently radiating periodic structures) for feeding 2-D phased arrays with a reduced number of phase shifter (PS) devices. Three design configurations using CORPS are proposed for 2-D phased arrays. The design model of phased array for these configurations considers the cophasal excitation required for this structure to set a strategic way for feeding the antenna elements and reducing the number of PS devices. Blocks of 2 × 3 and 4 × 7 CORPS networks depending on the configuration in the 2-D phased array are set strategically in the feeding network to generate the cophasal excitation required in the antenna elements. These design configurations used for feeding the antenna elements in the planar array geometry provide several advantages with respect to others in the scanning capability and the reduction of the number of PS devices of the array system. The full-wave simulation results for the proposed configurations in 2-D phased arrays provide a reduction in the number of PSs of until 69% for a scanning range of ±25° in elevation and ±40° in azimuth. The application of the raised cosine amplitude distribution could generate radiation patterns with a SLL_PEAK ≈ −19 dB and SLL_PEAK ≈ −23 dB for the design proposed configurations in all the scanning range.
