ABSTRACT

Long-term signal accumulation is an effective method to improve the detection of weak and slow small targets. However, the accumulation time is long, and the target echoes will move away from the unit and the Doppler unit, and the coherent accumulation is difficult. In this paper, the small target detection problem based on LTE signal is studied, and the target scattering variability is introduced. The system echo model based on LTE communication system is established. On this basis, the target echo distance walking and Doppler walking characteristics are analyzed. The echo coherent accumulation technique based on keystone transform and fractional Fourier transform (FRFT) is used. Based on the typical target scattering model, the influence of the target scattering characteristics on the accumulation effect is analyzed, and the simulation experiment is carried out under typical system conditions. The validity of the proposed algorithm and analysis is verified.
