| 摘要: |
| 针对线性调频雷达，对灵巧噪声干扰和前沿复制干扰的基本成分通过匹配滤波器后
输出的信号波形进行了分析。以产生相同的干扰效果为能量利用效率比较基准，推导了这两
种干扰方式各自所需的干扰信号能量的计算公式；在典型条件下，计算了这两种干扰方式所
需干扰信号能量的数值；在一般情况下，对这两种干扰方式的能量利用效率进行了比较。
分析结果表明，若前沿波形宽度为雷达发射信号宽度的1/n，则灵巧噪声干扰所需能量
仅为前沿复制
干扰所需能量的1/n。 |

| Abstract: |
| For chirp radar, the output waveforms of basic components of smart noise jamming
and front copy jamming passing through matching filter are analysed. Prod
ucing the same jamming effect is used as energy efficiency standard, and then th
e calculation expressions of needed jamming signal energy for the two jamming fo
rms are given. Under typical conditions, needed jamming signal energies for the
two jamming forms are calculated. Under general conditions, the energy efficienc
ies of the two jamming forms are compared with each other. It is pointed out tha
t if the width of the front waveform is 1/n of the width of the radar transm
itted signal, the energy efficiency of front copy jamming is 1/n of that of the
smart noise jamming. |
