Feature extraction method for micro-Doppler using LFM
2009
This paper mainly deals with the problem of extracting the micro-Doppler feature. The micro-Doppler can be regarded as the unique signature of the micro-motion target. Based on introducing the concept of the micro-Doppler, a method is proposed to extract the micro-doppler feature, which can estimate two micro-motion parameters, i.e., initial angle and frequency simultaneously. Then the mathematical formula of this method is derived. Finally, the computer simulation confirms theoretical analysis, providing theoretical foundation for micro-Doppler feature extraction.
