| 摘 要： | 谐波雷达的特点是能够在杂波背景中有效探测金属结目标.与普通雷达相比,多数人工金属物体的电磁转换效率低,作用距离近,因此,谐波雷达的应用受到限制.分析金属结目标的非线性散射特性并推导谐波雷达方程,讨论影响谐波目标探测器作用距离的因素,设计了一种基于三次谐波接收的近程金属结目标探测器.初步测试表明,三次谐波接收机可以探测近程金属目标,但是不仅要有很高的接收灵敏度,而且要有足够大的增益以满足对信号的检测.

| Abstract: | Harmonic radars are characterized by effectively detecting metallic junction targets in clutter background.Compared with common radars,the application of harmonic radars is restricted due to the low electromagnetic transform efficiency of the most man-made metallic objects and the short detecting range.A short-range detector for metallic junction targets based on triple harmonic reception is designed on the basis of the analysis for nonlinear scattering characteristics of metallic junction targets,derivatio... |
