Effects of resolution in microwave imaging

The resolution is very important for radar image. Using this technology and raising the resolution of radar image can be applied in cancer survey of medical application. In general, the radar image is measured in frequency domain. But now it can be measured in time domain by impulse time domain system at Da Yeh University. The impulse time domain system can gate the desired reflection signal from the target. The multipath and noise from environment can be gated out by the hardware gating function of impulse time domain system. The results of high-resolution radar image by both impulse time domain and traditional frequency domain will be discussed in this paper.
