发射端波束扫描:发射器通过一系列预定义的波束方向发送信号,接收器保持接收状态并测量每个波束方向的信号强度。 接收端波束扫描:接收器也可以进行类似的扫描,通过改变其接收波束方向来寻找最佳信号来源。 扫描完成后,系统会选取一个最佳的波束方向组合,这通常是信号强度最强或信噪比最高的波束对。 波束优化 在初始波束发...

Sharing of the frequency bands between radar and communication systems has attracted substantial attention, as it can avoid under-utilization of otherwise permanently allocated spectral resources, thus improving efficiency. Further, there is increasing demand for radar and communication systems that share th...
In a JRC system both the radar and the communication share the same platform and have a common transmit waveform. This example shows two approaches to utilizing a single waveform for both functions. The first approach uses PMCW. Such a JRC system can be considered as radar-centric, since ...

The historical development and current state-of-the-art of various joint wireless communication and radar sensing systems are reviewed and discussed in this study. Different kinds of systems are categorised according to their modulation waveforms and duplex schemes. Pros and cons of each category are...
内容提示: 1IEEE 802.11ad-based Radar: An Approach toJoint Vehicular Communication-Radar SystemPreeti Kumari, Junil Choi, Nuria González-Prelcic, and Robert W. Heath Jr.AbstractMillimeter-wave (mmWave) radar is widely used in vehicles for applications such as adaptive cruisecontrol and collision ...
This paper proposes a novel user cooperation approach in both computation and communication for mobile edge computing (MEC) systems to improve the energy efficiency for latency-constrained computation. We consider a basic three-node MEC system consisting of a user node, a helper node, and an acces...
The performance of the proposed transform in radar signal processing by analyzing the AF and in wireless communication systems based on the bit error rate (BER) analysis, is evaluated. The simulation result shows that HFrFT can be a suitable technique in joint radar and communication (JRC) ...
