Example Embodiment
[0026] A two-dimensional attitude measurement method of a launch vehicle based on a dual-frequency continuous wave transponder antenna, the steps are as follows
[0027] The first step is to establish a measurement system to measure speed and
[0028] The measurement system includes two continuous wave transponders carried by the arrow and a set of speed measuring radar on the ground;
[0029] Among them, such as figure 1 As shown, two continuous wave transponders are installed on the launch vehicle, and each continuous wave transponder corresponds to a set of operating point frequencies. A set of operating point frequencies includes one uplink point frequency and one downlink point frequency.
[0030] like figure 2 As shown, a set of multi-speed radar is deployed on the ground. A set of multi-speed radar includes two types of main station and auxiliary station. The main station is used to transmit 2 uplink point frequencies, and the auxiliary station is used to receive 2 c...

The invention belongs to the field of carrier rocket attitude measurement, and relates to a carrier rocket two-dimensional attitude measurement method based on a double-frequency continuous wave responder antenna. The method comprises the steps of establishing a measurement system, and measuring the measured speed sum, and acquiring the track of continuous wave responders according to the measuredspeed sum, and calculating the two-dimensional attitude of the carrier rocket according to the track of the continuous wave responders. According to the carrier rocket two-dimensional attitude measurement method based on the double-frequency continuous wave responder antenna, the track of the continuous wave responders is acquired based on the two rocket-carried continuous wave responders and a set of multi-speed-measuring radars on the ground, and the carrier rocket two-dimensional attitude is further calculated; and a carrier rocket measuring method having the characteristics of long time,long distance and medium precision is provided for a target field.
Description
technical field [0001] The invention belongs to the field of launch vehicle attitude measurement and relates to a two-dimensional attitude measurement method of a launch vehicle based on a dual-frequency continuous wave transponder antenna. Background technique [0002] At present, the attitude measurement of the launch vehicle is mainly carried out by the following three methods: [0003] 1. The carrier is equipped with a gyroscope to measure the attitude. [0004] The advantages are stable performance and high measurement accuracy. The disadvantage is that the output of the gyroscope is the angular velocity, and the angle needs to be integrated to obtain the angle; in the integration process, with the accumulation of time, a large system error will be introduced, and long-term attitude measurement data cannot be provided. [0005] 2. Optical equipment measures attitude. [0006] The advantage is high precision, and the disadvantage is that the optical equipment has a sh...
