Abstract
To meet the needs for mobile monitoring of electromagnetic environment in the battle-field,a battlefield electromagnetic signal detection system based on UAV platform is designed with electromagnetic signal perception and visual analysis technology.A frequency-center calculation mode based on improved FFT Pruning algorithm and Welch power spectrum estimation method is construct-ed,which can detect the frequency,bandwidth,power and other parameters of target signals in complex electromagnetic environment.It provides mobile,light and convenient means of electromagnetic signal monitoring for the troops(units).
