N2 - The analog to information conversion (AIC) via random demodulation (RD) has suffered the performance loss in reducing the sampling rate of linear frequency modulation (LFM) pulse compression radar, especially for the local non-sparse targets in high resolution environment. In this paper, a novel AIC scheme via the determinate chirp mixing sequence is proposed to deal with this problem. The determinate chirp mixing sequence is given in two modes with fixed time duration and fixed bandwidth, respectively. Due to the spread spectrum as well as the local narrowband characteristics in undersampling condition, the determinate chirp mixing sequence guarantees the reconstruction performance of local non-sparse targets with low hardware consumption. Performance analysis and simulation results are provided to demonstrate the effectiveness of chirp mixing sequence in the restricted isometry property (RIP) and reconstruction performance of non-sparse targets for LFM pulse compression radar.
