| Abstract: | A 0.67 THz Inverse Synthetic Aperture Radar(ISAR) imaging radar system is introduced. The radar detect range is 2 m-8 m, and the image resolution is 1 cm×1 cm. This radar takes two antennas to transmit and receive signals separately, and the transmitting signal is wide band linear frequency modulated continuous wave. The image radar can be used to safety inspection, nondestructive inspection and many other areas. The design scheme of the TR link is given, and the parameters of the link such as detect range, transmitting power, phase noise, resolution and receiving sensitivity are analyzed. The structure of the transceiver link is described in detail as well. The design lays theory foundation for the development of the imaging radar system on the following. |
