| 摘 要： | 从双基SAR干扰方程出发,将发射功率等与发射机有关的参数之积等效为干扰机在目标处探测到的回波功率强度,简化了干信比方程.推导了一定干信比下的干扰机等干信比覆盖区域,详细分析了此区域的特性及其与干扰机参数的关系.最后,从接收机已知角度讨论了有效干扰时,干扰机的等效辐射功率、干信比及干扰机到接收机距离三者之间的关系.仿真验证了理论分析的正确性.

| Abstract: | In this paper,from the interference equation of Bi-SAR,the product of parameters such as transmitting power etc,which are related to the transmitter is equated to the echo power intensity detected by the jammer,and the interference equation(J/S) is simplified.We derived the coverage area of J/S contours under the condition that J/S reached a feasible value.Then the characteristics of the area and its relationship with jammer parameters are analyzed.Finally,we discuss the relations among the value of J/S,the... |
