Josephson parametric amplifier (JPA) engineering is a significant component in the quantum two-mode squeezed radar (QTMS) to enhance, for instance, radar performance and the detection range or bandwidth. We simulated a proposal of using engineered JPA (EJPA) to enhance the performance of a QTMS radar. We defined the signal-to-noise ratio (SNR) and detection range equations of the QTMS radar. The engineered JPA led to a remarkable improvement in the quantum radar performance, i.e., a large enhancement in SNR of about 6 dB more than the conventional QTMS radar (with respect to the latest version of the QTMS radar and not to the classical radar), a substantial improvement in the probability of detection through far fewer channels. The important point in this work was that we expressed the importance of choosing suitable detectors for the QTMS radars. Finally, we simulated the transmission of the signal to the target in the QTMS radar and obtained a huge increase in the QTMS radar range, up to 482 m in the current study.
约瑟夫森参量放大器（JPA）工程是量子双模压缩雷达（QTMS）的一个重要组成部分，例如可用于提升雷达性能、探测范围或带宽。我们模拟了一项使用工程化JPA（EJPA）来提高QTMS雷达性能的方案。我们定义了QTMS雷达的信噪比（SNR）和探测范围方程。工程化JPA使量子雷达性能得到显著提升，即相比于传统QTMS雷达（相对于最新版本的QTMS雷达，而非经典雷达），信噪比大幅提高约6 dB，并且通过少得多的通道显著提高了检测概率。这项工作的重点在于我们阐述了为QTMS雷达选择合适探测器的重要性。最后，我们模拟了QTMS雷达中信号向目标的传输，在当前研究中，QTMS雷达的探测范围大幅增加，达到了482米。
