| Summary: | A simple method of passive localization is proposed in this article. The proposed approach is located a on the ground or in the air stationary target using the satellites in different signal Doppler frequencies. After the localization principle and algorithm are introduced, the relationship between the positioning precision and the measurement precision of Doppler changing rate, carrier wave frequency, height assumption error, orbit measurement of satellite are analyzed, and then some simulation results are given. Our proposed positioning method can achieve the positioning precision of 5 km within the scope of the radius of 200 km, which is much better than the traditional method based on direction finding on the positioning precision of a few tens of kilometers.
