Ranging algorithm based on process measurement for low-altitude radio fuzes

Abstract

A ranging algorithm based on process measurement was proposed for low-altitude radio fuzes with wide range of action and low request of absolute ranging precision. For those particular applications, a conception of relative burst height was given to control the initiation point of a fuze instead of the absolute burst height. The received echo power was analyzed and its relationship with the relative burst height was derived. The basic principle and implementation of the ranging algorithm were discussed and the simulation results were given including anti-white Gaussian noise performance and anti-active jamming performance. The results proved the feasibility of the ranging algorithm based on process measurement. It could be used to help the further researches of low altitude radio fuzes.
