在本章中，我们介绍了一种基带接收器，它允许对类似scat处理的输出进行分析处理，也可以应用于RF信号。对基带SCAT （BSCT）的输出与传统匹配滤波器对两个紧密间隔散射体的输出进行了分析比较。结果表明，蝙蝠启发的光谱图变换比传统的匹配滤波器具有更好的距离分辨率。对结果进行了解析推导，然后通过一组实验室超声实验，使用虚回波和真实目标进行了验证，以评估该算法在操作硬件限制和传播效应方面的鲁棒性。
In this chapter, we have presented a baseband receiver that allows an analytical treatment of the output of a SCAT-like processing and that can also be applied to RF signals. The output of the Baseband SCAT (BSCT) has been compared analytically with that of a conventional matched filter for two closely spaced scatterers. Results have shown that a bat-inspired spectrogram transformation can provide better range resolution performance than that of a conventional matched filter. The results have been derived analytically and then verified with a set of laboratory experiments at ultrasound, using phantom echoes and real targets, to assess the robustness of the algorithm with respect to operational hardware limitations and propagation effects.
