Application of Linear Predictive Coding for Doppler Through-Wall Radar Target Tracking |
Abstract | ||
|---|---|---|
In this letter, a target tracking approach, which combines short-time Fourier transform (STFT) and linear predictive coding (LPC), is proposed for a Doppler through-wall radar. The LPC is applied to extend the known echo data in each STFT sliding window, thus helping in improving the estimation accuracy of target instantaneous frequency. Compared with the traditional LPC process which determines the prediction data size empirically, the proposed approach takes advantage of the fitting error array as a control parameter to intelligently adjust the data size and reduce the prediction error. Moreover, the proposed approach can also enhance the radar processing efficiency by preventing the unqualified prediction data, which is of great importance for real-time detecting applications. Series of experimental measurements are presented as a preliminary assessment of the proposed approach. |
