In the ionospheric monostatic system the echo is af- fected by systematic error. A real-time method using the special characters of direct wave existing in monostatic radar to correct systematic error is advanced. In the condition of large-amplitude direct wave, time delay of maximum amplitude of echo is consid- ered as system time delay; in the condition of small-amplitude direct wave, the mathematical model of time delay error is built to approach after direct wave test. And a method using large-ampli- tude direct wave to correct phase distortion is advanced. It achieves good effect using this method in practice, which can im- prove the quality of sound result obviously.
