论文摘要
通过引入正交相移键合（QPSK）线性调节（LFM）信号，提出了光子辅助的联合雷达系统和实验证明。 LFM信号是载体抑制的单层带，该单侧调制在一个双平行的MACH-ZEHNDER调制器（DPMZM）的光载体上，这是双偏置双极化的双极化MACH-ZEHNDER调制器（DPOL-DPMZM）。 DPOL-DPMZM的另一个DPMZM偏向于在光载体上实现QPSK调制的智商调节器。在光电探测器中进一步合并并检测到来自DPOL-DPMZM的极化正交光学信号，以生成QPSK-SIC的LFM信号，该信号用于实现有效的数据传输和高性能雷达功能，包括范围和成像。进行实验。雷达范围的检测小于4 cm，分辨率为14.99 cm*3.25 cm的ISAR成像，并且数据速率为105.26 mbit/s的通信得到了成功的验证。
A photonics-assisted joint communication-radar system is proposed and experimentally demonstrated, by introducing a quadrature phase-shift keying (QPSK)-sliced linearly frequency-modulated (LFM) signal. An LFM signal is carrier-suppressed single-sideband modulated onto the optical carrier in one dual-parallel Mach-Zehnder modulator (DPMZM) of a dual-polarization dual-parallel Mach-Zehnder modulator (DPol-DPMZM). The other DPMZM of the DPol-DPMZM is biased as an IQ modulator to implement QPSK modulation on the optical carrier. The polarization orthogonal optical signals from the DPol-DPMZM are further combined and detected in a photodetector to generate the QPSK-sliced LFM signal, which is used to realize efficient data transmission and high-performance radar functions including ranging and imaging. An experiment is carried out. Radar range detection with an error of less than 4 cm, ISAR imaging with a resolution of 14.99 cm*3.25 cm, and communication with a data rate of 105.26 Mbit/s are successfully verified.
