Projectile-borne meteorological information detection dropsonde integrating micro-sensors

The projectile-borne meteorological information detection dropsonde is designed to be launched by a missile and dropped at altitude as the missile reached its peak to detect real-time meteorological information as the device falls to the surface. The high acceleration shock deriving from missile launch, violent changes of atmospheric parameter and stochastic disruptions from external environment are the main difficult to design this device. To deal with those problems, we apply sensors based on MEMS technology as their high performance in accuracy, anti-overload and easy integration, we explore best locations on the dropsonde body for sensors based on simulation, we develop effective arithmetic for data processing. At last, the performance of dropsonde is verified by some ground static experiments.
