Abstract

In the flight test of the airborne airdrop system for transport aircraft, it is necessary to measure the operating speed and trajectory of the airdropped cargo in the cabin to verify whether the function and performance of the airborne airdrop system for aircraft meets the requirements of combat wood targets. According to the airdrop environment and mission characteristics, this paper constructs a spatial positioning model based on the time difference of arrival. The crosscorrelation interference and non-line-of-sight effect elimination technology is adopted to achieve rapid capture of weak signals and improve the accuracy of tag positioning. The position accuracy of the test system based on UWB is better than 0.15 meters, and the frame rate is 25 frames. This method can also be applied to the measurement of suspension and other tasks such as hanging swing measurement.
