两种功率倒置阵列天线调零模型的等效性分析

Equivalence Analysis on Two Kinds of Power Inversion Models for Zero-Trap in Antenna Array

在对卫星导航接收系统中两种常见的功率倒置阵列天线调零模型:基于参考信号的最小均方误差模型和线性约束条件下的最小功率模型,利用分块矩阵求逆特性从理论上证明了这两种模型之间的等效性,并针对不同模型的特点指出了这两种模型各自不同的应用场合,通过仿真对理论分析的有效性进行了验证,从而为卫星导航接收系统中的抗干扰调零天线的理论建模、仿真设计和实际应用提供了新的参考。

Now there are two common kinds of power inversion models for zero-trap in antenna array of the satellite navigation receiving system. One is the LMS （Least Mean Square） model with the reference signal, the other is LCMP （Linear Constrained Minimum Power） model. After the two models are briefly analyzed, their equivalence is theoretically approved though the inverse characteristic of the block matrix. Their different adaptive situations are discussed according to their characteristics. The validity of the theory is demonstrated through the simulation. This is the new reference for theoretical model construction, simulation, designation and application of anti-jamming zero-trap antenna in the satellite navigation receiving system.
