Ultra-wideband Radar SignalsGenerated withTwo-channel
Yonglun Wan, Youxin LuandXuegang Wang · 2006
Synthesis ofultra-wideband (UWB)linear frequen- cymodulated radarsignals isaveryimportant technology for microwave imaging, target identification anddetection oflow radar-cross-section (RCS)targets. In thispapera new methodofUWB radarsignals generated withtwo-channel is presented. The realization structure isgiven,and the principle ofsignal synthesis isanalyzed. Atthesametime, an automatic adjustment measureofsignal phaseisproposed because ofdiscontinuity ofsignal phaseinthismethod. The simulation andexperiment results showthatradarsignals withlargeinstantaneous bandwidth canbegenerated by meansofthismethodonthecondition thatthehigh-speed digital devices arelimited.
