摘要：

针对低空区域的防控问题，提出分布式组网探测体制。采用基站式发射、分布式接收、基于到达时间(time of arrival, TOA)的定位、组网探测等手段,采用分层跟踪与航迹管理有效抑制低空探测场景下的虚假航迹,适宜低空目标探测场景。通过引入分布式扩展系数和低空覆盖系数，可对系统进行有效评估。在正方形与正六边形部署场景下,仿真验证了其威力与精度性能,与传统单基地雷达相比,该体制具有较好的低空探测与扩展能力。

Abstract:

Focusing on the detection of the low-altitude target, the distributed network detection system is proposed which adopts the methods of the base station transmission, distributed reception, time of arrival (TOA) location and network detection, and uses the layered tracking and trajectory management to effectively reduce the false trajectory. The system is suitable to the detection of the low-altitude target. It is suggested to use the parameters of the distributed extensibility and low-altitude coverage to assess the system. The simulation result under square and hexagon deployments verifies the detection ability of coverage and accuracy of the system. Compared with traditional monostatic radars, it has fine low-altitude detection and expansion capability.

Key words: low-altitude target, distributed, radar network, distributed extensibility coefficient, low-altitude coverage coefficient
