研制了一种用于储罐液位测量的新型低功耗微波传感器。通过使用锁相环控制的选通振荡器，该FMCW雷达可以在标准的4-20 mA环路中工作，而无需额外的电源电源。所选择的系统设计具有振荡器快速建立时间以实现准连续扫频的特点，从而形成了精确、稳定和可靠的液位测量系统。
A novel low-power microwave sensor for level gaging in storage tanks has been developed. By using a PLL-controlled gated oscillator this FMCW radar can be operated in a standard 4-20 mA loop without additional supply power. The chosen system design features a fast settling time of the oscillators to achieve a quasi-continuous frequency sweep, resulting in a precise, stable and reliable level measuring system.
