| 摘 要： | 针对校正软件化雷达接收通道不一致性的查表法 ,深入研究了接收通道增益的估计方法 ,该方法首先在天线阵列所在平面设置的一个校正源 ,运用信号子空间对信号DOA和通道增益的约束关系对通道增益进行估计 ,在未知校正信号DOA时可通过迭代的方法获得二者的一致估计。仿真证明了该方法的有效性。

| Abstract: | This article concentrates its attention on the searching table method of calibrating software radar receiving channel mismatch, and studies the method of sensor gain estimation in depth. The method requires putting a calibration source in array plane at first, then using the constraint of DOA angles and sensors' gain in the signal subspace , the estimation of sensor's gain can be obtained. If the DOA of the calibration source is unknown, the consistent estimation of them can be got by iterative method. The usefulness is demonstated by simulations. [ |
