The intelligentized recognition of oblique propagation modes

FAN Jun-mei LU Zhuan-xia JIAO Pei-nan(China Research Institute of Radiowave Propagation,National Key Laboratory of Electromagnetic Environment,Qingdao Shandong 266107,China)  
A new method of obtaining high-quality ionograms adopting numeric statistics and morphology operators in digital image processing is described.All parameters of propagation mode,such as frequency band,group delay and signal energy etc.,can be obtained from normal oblique ionogram by the intelligentized process utilizing improved First-Local-Maximum and Bound-Condition-Extrapolation methods,and combining statistical property of sounding traces.
