Doppler Signal Simulation and Analytic System for Radio Fuze

A system for simulating and analyzing the Doppler signal of air-target fuse is established by constructing two parts: Doppler signal testing with simulation and Doppler signal analysis. The first part establishes the near-field target characteristic model where the Doppler spectrum in different encounter condition is obtained. The second part mainly deals with a general purpose hardware platform to obtain and process the Doppler signal as well as a software to estimate the Doppler spectrum. The model and the result of Doppler spectrum analysis were verified by experiments.
