摘要

提出的FMCW雷达系统，工作频率为300 GHz，使用超宽带44.41 GHz。由于输出功率相对较高，为4 dBm，接收器噪声系数为15 dB，因此可以实现高动态范围。一维单目标测量表明，在全带宽下频率响应平坦，距离分辨率为3.29 mm(无窗函数的3 db宽度)。最后，土壤上物体的SAR图像证明了高分辨率成像应用的潜力。

An ultra-high resolution radar-system operating at 300 GHz

The presented FMCW radar system, operating at 300 GHz, using an ultra-wide bandwidth of 44.41 GHz. Due to the relatively high output power of 4 dBm and the receiver noise figure of 15 dB, a high dynamic range can be achieved. One-dimensional single target measurements demonstrate a flat frequency response in the full bandwidth and a good range resolution of 3.29 mm (3-dB width without window function). Finally a SAR image of objects on the soil prove the potential for high resolution imaging applications.
