基于复杂海情下的小目标探测雷达系统

Small target detection radar system based on complex sea conditions

摘要:

复杂海情背景下的小目标探测是海面搜索、监视系列雷达的一项关键技术，传统雷达很难保证在较低的虚警概率下，可靠地检测海面小目标。基于复杂海情下海杂波散射功率特性分析，结合高分辨力波形设计、天线快速扫描技术与海面小目标检测技术等雷达系统设计给出了在复杂海情背景下提高小目标检测性能的技术途径，在较低虚警概率下，保证有效、可靠地检测出复杂海情下的海面小目标。

Abstract:

The small target detection in the complex sea context is a key technology for the sea search and surveillance series radar. The traditional radar system cannot guarantee reliable detection performance when encountering with these small targets. Based on the analysis of the scattered power characteristics of the sea clutter in complex sea conditions, a technical way is proposed to improve the performance of small targets in complex sea conditions by combining radar system design and sea surface small target detection technology, and ensure that under the low false alarm probability, small targets can be detected effectively and reliably on the sea.
