摘　　要：针对目前使用的电容式、重锤式等料位仪存在的适应性和稳定性较差、测量精度不高等问题,利用FMCW雷达的测距原理对FMCW雷达在煤粉仓料位测量中的应用进行了建模和模拟仿真。实验结果表明,FMCW雷达仿真系统能够有效的测量煤粉仓的料位高度,为火电厂的煤粉仓料位的测量提供了一种新的方法。Aiming at the problems such as the worse compatibility and the worse stability and the lower measure precision,which exists in the instruments of measuring the material level now,an FMCW radar for measuring coal level is modeled and simulated with distance measuring.The result indicates,the FMCW radar system can effectively measure the coal level,it provides a new method for measuring the coal level of the power plant.
