If the variation of input weak signal can be reflected by certain word length, the output SNR mainly depends on the word length of adaptive operations.

如果某个量化字长能反映出输出弱信号的变化，输出信噪比主要取决于自适应运算的字长。

However, the traditional weak signal detection method, input signal to noise ratio threshold are subject to certain restrictions, it is difficult to further reduce.

然而，传统的微弱信号检测方法，输入信噪比门限受到一定限制，很难进一步降低。
