Abstract

Chirp stepped-frequency radar waveform possesses large bandwidth generally. Echo Reconstruction from electromagnetic computed RCS of each frequency is a computationally intensive task and encounters real time problem for high speed targets. Using linear radar target theory and FFT interpolating method, a new method of dynamic target echo reconstruction of chirp stepped-frequency radar was proposed. The new method focuses on the real-time echo generation of high speed targets under Chirp stepped-frequency pulses. The numerical simulation was performed to illustrate the validity of the proposed method.

Key words： chirp stepped-frequency radar; dynamic target echo; simulation reconstruction; linear radar target theory; FFT interpolating and restoring
