视频积累网络雷达对SWⅠ目标检测性能分析

Analysis of the Detection Performance of Non-coherent Integration Network Radar to Swerling I Targets

网络雷达实现了雷达与雷达对抗的一体化,是雷达系统与雷达对抗系统发展的新趋势。视频积累网络雷达作为多脉冲积累网络雷达的一种重要形式,对其检测性能进行研究具有重要意义。而雷达性能与目标紧密相关,要对雷达性能有一个全面而深刻的了解,就必须对其在不同目标模型时的性能进行研究。文中研究了在总发射功率一定的条件下,视频积累网络雷达多输入多输出(MIMO)模式和MW(Mobile Window)模式对SWⅠ(SwerlingⅠ)目标的检测性能,并在此基础上进行了仿真。结果表明视频积累网络雷达MIMO模式和MW模式对SWⅠ目标检测能力是不同的,为网络雷达工作模式的选择提供了一定的理论基础。

Network Radar realizes the integration of the radar and radar countermeasures ; it is a new trend of radar and radar countermeasures system. The research about non-coherent Integration Network Radar who is one of the most important kinds of pulse integration network radar is very important. And radar detection performance based on different target models is necessary if someone wants to find out the performance of radar generally and profoundly. At first, it introduces MIMO model and MW model of the noncoherent Integration network radar models according as the different ways of information processing; then some relevant formulas are deduced. In succession, it probes into how to analyze the detection performance of the MIMO model and MW model of network radar models to SW I targets when the total power of single pulse of the transmitters is definite. Through the simulations of the detection performance of these network radar models, the results show that the MIMO model and MW model of network radar models have different detection performance to the SW Ⅰ targets and they are very significant to solve the question how to select the network radar model.
