| 摘 要： | 简要介绍国外现有微波测量固体推进剂瞬态燃速的方法。提出一种建立于单边带调制技术的新微波测量法。新法采用了一个微波燃速传感器,它能直接获得微波多普勒变化量,具有低值、便携的优点,因此适用于工程现场测试。本文比较了滤波法和相移法,采用相移法能进一步提高瞬态燃速的分辨率。

| Abstract: | Available method by using microwave for measuring solid propellant transient regression rate are briely reviewed. A new measurment method based on the SSB microwave modulating techniqe is proposed in the paper. A microwave regression rate sensor is used to measure the microwave Doppler shift directly.The new method has adventage of low cost and can be used in site testing.
There arc two methods related to SSB in the paper. The filter method and phasing method are compared. Results show that the phasing method has higher transient regression rate resolution than the filter method. |
