But if the Doppler frequency offset exceed the capture range of PLL, the carrier synchronization will fail.

但是，一旦多普勒频移超出了锁相环的频率捕捉范围，就无法完成载频同步。

The narrower the loop filter bandwidth the smaller the achievable phase error. This comes at the expense of slower response and reduced capture range.

滤波器的带宽越窄，得到的相位差越小，其代价为响应变慢俘获范围变小。

Experimental results demonstrate that it is characteristic of wide capture range, short capture time and satisfactory performance under noisy environment.

实验结果表明，它具有捕捉范围宽、捕捉时间短和在噪声背景下有令人满意的性能等特点。

Compared with conventional PLL threshold extended demodulator, it features wider capture range, shorter capture time and significant improvement in threshold level.

与常规pll门限扩展解调器相比，它具有捕获范围宽，捕获时间短，门限改善量显著等优点。
