Abstract

For wideband LFM signal, the paper presents a mathematical model of echo from spatial maneuvering targets and analyzes the impact of high acceleration and maneuvering on range profile quantitatively. According to invariable chirp rate, a range profile compensation algorithm based on difference is proposed. It can estimate the chirp rate accurately by FFT without acceleration and velocity estimation, so the influence of high-order coefficient is eliminated. Due to its no phase estimation, this algorithm has good anti-noise performance. In addition, the sample rate does not need to be higher than the bandwidth of LFM signal, so the processing speed is improved. The analysis is proved by simulation results.
