Abstract: For the problems of the conventional missile environment parameters measurement system, the scattered measuring point, the large range margin and the heavy cable are included, a reuse network measurement scheme of the projectile surface field parameters is proposed, which is based on the optical fiber wavelength division multiplexing and space division multiplexing technology. The temperature, pressure, strain and other environmental parameters can be effectively measured at the same time in the system, and it can be measured up to 320 channels. The key technologies of the large capacity fiber sensor network are analyzed, and the engineering application analysis on the missile is described, which provides a new idea and solution to effectively meet the small, light, high sensitivity and the volume of the projectile.
