error of final frequency的意思|示意

The former determines the frequency range which should be revised by the hot tracking circuit, while the later is the final frequency error of the local oscillator.

同时也提出了热跟踪后本振频率跟踪误差项。分析前者，可以决定热跟踪电路应予修正的频率范围，而后者则是跟踪本振最终的误差。

Phase errors is introduced in echo demodulation process because of the frequency synchronization error, and then, the final focus result will be deteriorated.

在接收端解调过程中，该频率同步误差会引入一定的相位误差，进而影响下一步的成像处理。
