摘　　要：阵列模型误差对阵列信号处理影响严重,且建模困难,实际工程中通常采用内插技术进行阵列误差校正。在对导向矢量内插法进行分析的基础上,提出运用该方法的4个条件,即稳健性、可插性、单调性和叠加性,并给出了定义。这4个条件是误差校正后的阵列有效工作的前提,仿真实验验证了该结论。提出的条件对工程实践具有一定的指导价值。Array signal processing is adversely affected by array model errors. Considering that model errors are difficult to be modeled,the interpolation technology is usually used to calibrate them in practice. Based on the analysis on the method of steering vector interpolation,four defined requirements,i.e. robustness,insertability,monotonicity and superposition are proposed to apply this method. Those requirements are prerequisites for array working. This conclusion is demonstrated by the results of simulation experiments. Therefore,the proposed requirements are valuable in engineering practice.
