Numerical analysis of distortion of chirp pulse waves propagated through turbulent media

Attention is paid to a chirp radar system and the mean pulse intensity of received pulse waves distorted by the ionospheric turbulence is analyzed. The analysis is based on the two frequency moment equation in which the multiple scattering due to inhomogeneous turbulent media is precisely introduced. It is shown through some quantitative analyses that a chirp radar system is not susceptible to the ionospheric turbulence in view of mean pulse intensity distortion as compared with the system without pulse compression technique. As a result, the chirp radar system may be useful for sensing a target in strong turbulent media with high resolution accuracy
