Study on Positioning High Dynamic Distributed Platforms Based on LFM Signal

Proposed a positioning method for high dynamic distributed platforms combined two-way microwave ranging with short baseline interferometer angle measurement. Effectively suppressed Doppler interference while ranging based on the frequency and time characteristics of broadband Positive and negative slope of the LFM (linear frequency modulation) signal. Also proposed precise angle measurement method with ambiguity resolution by frequency measurement. Finally, analyzed and experimental verified the validity and accuracy of the positioning method.
