| 摘要: |
| 如何维持雷达检测系统恒定的虚警率是现代雷达技术和信号处理技术中重要的问题之一。为使雷达检测系统在复杂的杂波环境中获得恒定的虚警率，就需要有高性能的恒虚警(CFAR)处理器。本文提出的新型CFAR处理器选择一个与被检测距离单元的值相接近的均值来作为CFAR的门限，从而使这种处理器具有能够及时反映外部杂波环境变化的自适应性;它硬件实现简单，具有很好的抗多目标效应、抗杂波边缘效应、抗大目标“吃”小目标效应以及降低(CFAR)损失的性能。 |

| Abstract: |
| How to maintain the false-alarm-rate constant of radar detecting system is one of the important problems in modern radar technology and signal processing technology. In order to obtain constant-false-alarm-rate in the complex clutter surrounding，radar detecting system must have a constant-false-alarm-rate processor (CFAR Processor). The AC-CFAR processor discussed in this paper is a new processor. Its CFAR threshold is implemented by selecting a mean value which approaches the detected distance-cell value. On the basis of simple hardware-implement，the AC-CFAR processor has an adaptive performance which can timely reflect the changes of external clutter，and a very good perfermance of anti-multitarget effect and antic1utter edge effect as well. It can also resist the effect ofb“ig target eat small target” and reduce CFAR loss. |
