求翻译：本文分析了七个信号的测距能力，分别是正弦信号、白噪声信号、调频信号、二进制伪随机序列、扫频信号、方波信号、二次扫频信号。通过原信号与延时后的信号互相关，分析信号自身的测距效果；再通过引入噪声信号互相关后的波形图以及最大值对应的时间，分析信号对噪声的抑制能力。经对比分析，得出二进制伪随机序列的测距性能最佳。是什么意思？

This paper analyzes the ranging capability of the seven signals are sinusoidal signals and white noise signal, FM signal, binary pseudo-random sequence, the sweep signal, square wave signal, the second sweep signal. The original signal and the delay signal cross-correlation a
