一种新的阵列通道失配仿真模型

A New Array Channel Mismatch Model for Simulations

该文提出一种阵列通道失配仿真模型,该模型由4个子滤波器级联构成,各个子滤波器分别控制幅度起伏、带宽、群延迟起伏和平均群延迟偏差等滤波器指标。设计结果表明,该模型具有设计准确、可控性强的特点, 适用于自适应阵列通道失配的仿真。

A new array channel mismatch model for simulations is proposed. The model consists of four sub-filters which separately control the four specifications of channels： amplitude variation, bandwidth, group delay variation and absolute delay offset. It is shown from design results that the channel mismatch model proposed is accurate and flexible, hence the model is suitable for the simulations of adaptive arrays.
