Ranging error analysis in LFM radar under influence of Doppler frequency

This paper, starting with the time and spectrum domain characteristics of the LFM pulse and its matched filter, analyzes the ranging error generated by the Doppler frequency shift in the received signal, and presents a range error correction model for the LFM pulse compression radar, which is proved applicable through further computer simulation and tracking data analysis. Cautions are also proposed as to the practical engineering application of the correction equation.
