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.
