We demonstrate the use of stimulated echoes for high-speed phase-modulated signal processing. The specific example chosen here involves the compression of biphase-coded pulses-a technique widely used in radar systems to achieve high range resolution and high signal-to-noise ratios. Experimental results obtained with the 5- and 13-bit Barker codes are presented, along with the measurements of a system's dynamic range and signal-to-noise enhancement. Advantages of this technique over the existing methods for signal processing are discussed.
我们展示了受激回波在高速相位调制信号处理中的应用。这里选择的具体示例涉及双相编码脉冲的压缩——这是一种在雷达系统中广泛使用的技术，用于实现高距离分辨率和高信噪比。给出了使用5位和13位巴克码获得的实验结果，以及系统动态范围和信噪比增强的测量结果。讨论了该技术相对于现有信号处理方法的优势。
