摘要
提出了一种利用单个外辐射源与单一接收设备协同工作对空中运动目标无源定位的新方法。将ICA技术用于直达波和反射波的分离中,对分离后信号进行时间特征提取,以确定来波的到达时间差。分析了信号独立观测器的构成,并依此提出球面阵列接收天线的设计方案。
A new passive location method to locate moving targets in the sky by a cooperative work of an outside-radiation source and an electronic reception equipment is proposed.The ICA technique is used to separate direct wave and reflected wave.The time characteristics of separated signals are extracted to confirm the time-difference of incoming wave.The structure of the signal independent observer is analyzed.The design scheme of the spherical array receiving antenna is put forward according to analysis.
