A Radio Speed Measuring Device for Measuring the Landing Speed of Airdrop Products

设计了一种用于空投产品着地速度测量的无线电测速装置,该装置将无线电引信模块加装到被测物体内,结合运动时产生的多普勒频率实现对空投产品着地速度的测量。与常规测量装置相比,该装置具有较高的可靠性、测速精度、耐冲击过载能力。经外场验证,在产品落角大于45°着地情况下,该装置的测速精度满足测速要求,可以用于空投产品着地速度的测量。

The landing speed directly affects the electrical and mechanical properties of the airdrop products, which is one of the important parameters of the products. This paper designed a kind of radio speed measuring device for measuring landing speed of airdrop products. The device installs radio fuze module into the object under test and realizes the measurement of landing velocity of airdrop products by combining the Doppler frequency generated in motion. Compared with the conventional measurement method, the device has higher reliability, speed accuracy, shock resistance and overload capacity. The field test shows that the measuring accuracy of the device meets the requirement of measuring the product's velocity when the product's angle of landing is greater than 45°. It can be used to measure the landing velocity of the airdrop product.
