Abstract	It is efficient to enlarge the radar bandwidth based on multi-band fusion. However, the former research on multi-band fusion did not take velocity into consideration. When the velocity is very high or pulse width is long, ignoring the impact of high speed the range resolution will deteriorate heavily. In this paper the authors develop a new method of forming high resolution range profile of fast moving targets based on multiple radars using wideband LFM (linear frequency modulated) signals. This method gets each wide-band spectrum pulse-compressed and velocity-compensated in frequency domain before multi-band fusion. The theoretical analysis and computer simulations show that the proposed method can effectively fuse multi-band signal of radar target at high speed and in small size into an enlarged band, thus we can improve the range resolution. Also it provides the potential for Ultra-Wide Frequency Band UWB processing of real-world fast moving target data collected by separate wide-band radars.
