Abstract

The availability of ultra wide band radar (UWBR) systems with their subtle characteristics enhance the complexity of achieving electromagnetic compatibility (EMC). For efficient applications an UWBR system requires a total radiated peak power of the order of a few GW with a transmitted pulse of several hundred picoseconds and a corresponding rise and fall time. The generation and coherent radiation of several hundred picoseconds double exponential pulse, with a spatial extent of several centimeters, requires special EMC considerations to achieve intrasystem EMC. For long range wide area surveillance radar requiring effective radiated power in the GW range makes the intersystem EMI problem effectively insurmountable. This paper highlights the electromagnetic interference (EMI) and compatibility aspects pertaining to UWBR systems. The electromagnetic environment (EME) and its impact in intrasystem and intersystem EMI problems, their control and the applicability of the existing standards are critically analyzed and discussed.

超宽带雷达(UWBR)系统在EMC场景下的影响

超宽带雷达(UWBR)系统的可用性及其微妙的特性增加了实现电磁兼容(EMC)的复杂性。为了高效应用，UWBR系统需要几吉瓦量级的总辐射峰值功率，发射脉冲为几百皮秒，并有相应的上升和下降时间。几百皮秒双指数脉冲的产生和相干辐射，空间范围为几厘米，需要特殊的电磁兼容考虑来实现系统内电磁兼容。对于需要GW范围内有效辐射功率的远程广域监视雷达来说，系统间电磁干扰问题实际上是无法克服的。本文重点介绍了超宽带无线电系统的电磁干扰和兼容问题。对电磁环境及其对系统内和系统间电磁干扰问题的影响、电磁干扰的控制和现有标准的适用性进行了批判性的分析和讨论。
