Finally, these judged variables adjust the local oscillating frequency to track the carrier frequency by NCO.
最后用这些变量调节本地振荡频率，以跟踪载波频率。

The towing body of towing profiler is a carrier that can realize Wave-form track movement and measure real-time multi-parameters of ocean.
拖曳式剖面探测拖体是一种能做波浪式轨迹运动的载体，可对海洋进行实时多参数剖面探测。
