The Characteristics Analysis of Ionospheric Clutter in Multiple Dimensions for HFSWR
The unwanted components of radar echoes from the ionosphere seriously affects the detection performance of high frequency surface wave radar (HFSWR). Because the variation of electron density in the ionosphere is irregular, ionospheric clutter can be divided into various types and behaves in different manner. This report explores the characteristics of various ionospheric clutter and analyzes these characteristics in the time, range, doppler, and angular domain. In the past two years, we collected a great deal of real data from a HFSWR system deployed in Weihai, China. We firstly investigate the ionospheric clutter characteristics both experimentally and theoretically in terms of the transform functions. Then, we will propose corresponding suppression methods for middle latitude ionospheric clutter in the future work.
