雷达组网协同探测系统工程设计与实现

Engineering Design and Implementation of Radar Network Cooperative Detection System

受日益复杂的目标特性、电磁环境和地理环境的影响,单装雷达探测效能受到极大的制约,雷达组网协同探测技术为提升单装和体系内目标探测能力、抗干扰能力和情报保障能力方面提供了技术机理。雷达组网协同探测系统可分为任务级、参数级和信号级三类。对于任务级和参数级组网协同探测系统,为实现网内雷达协同作战、整体探测、区域对抗、情报共享等主要功能,在工程设计上主要完成任务筹划、协同管控、信息融合、效能评估、协同交战指挥控制以及组网通信等功能,实现对单装和系统的体系赋能。信号级分布式协同探测系统主要解决时间、频率和空间同步问题,形成双/多基地信号协同体制,实现收、发相参体制信号级得益,实现等效“大雷达”效能。

Affected by the increasingly complex target characteristics,electromagnetic environment and geographical environment,the detection effectiveness of single-unit radar is greatly constrained,and the radar network cooperative detection technology provides a technical mechanism to enhance the detection capability of single-unit and intra-system targets,anti-jamming capability and intelligence support capability.Radar network cooperative detection system can be divided into two categories:task level/parameter level and signal level.For the task-level and parameter-level network cooperative detection system,in order to realize the main functions of radar cooperative operation,overall detection,regional confrontation and intelligence sharing within the network,the engineering design mainly accomplishes the functions of task planning,cooperative management and control,information fusion,performance evaluation,cooperative engagement command and control,and network communication,etc.,so as to realize the system empowerment for the single-unit and system.The signal-level distributed cooperative detection system mainly solves the problem of time,frequency and space synchronization,forms a dual/multi-base signal cooperative system,realizes the signal-level gain of the receiving and sending phase reference system,and realizes the equivalent “big radar” performance.
