Polarization filtering technique is widely used in many fields, for example interference suppression of sky wave in HF radar. Based on the actual wave data of both signal and clutter, the cause for generation of error, way of error reduction and improvement of SIR by using polarization filtering technique are discussed.

极化滤波技术在高频雷达抗天波干扰等领域有着广泛的应用，结合实际雷达测得的目标回波和干扰回波矢量数据，对极化滤波误差产生的原因、减小误差的方法以及利用极化滤波方法提高信干比的有效性进行了详细分析。

Secondly, when kalman filter has reached steady state its error covariance will have a very small stationary value, namely filter dropping off'. Thirdly, the traditional kalman filter cannot adjust its filter parameters with statistic characteristic of the noise. To overcome the deficiency of kalman filter, an SVD-based adaptive kalman filter is put forward in the paper. The filter restrains the filter divergence by matrix singular value decomposition. The eigenvalues and eigenvectors of the matrix are insensitive to tiny change of matrix element and acceptable error.

然而，传统的卡尔曼滤波器存在以下问题：问题一，因噪声统计特性估计不准确和计算机舍入误差引起的滤波发散现象；问题二，在卡尔曼滤波器达到稳态时，其误差方差阵将饱和使其对信号的突变变得不敏感，问题三，传统的卡尔曼滤波器对滤波参数无自适应能力，不能随着噪声统计特性的改变而调整自身的滤波参数。

Finally, suspected mechanical flexure of the telescope mirror and dovetail mount attachment occasionally adds additional error to the pointing, causing the total error in these data to exceed the 11 arc-m limit imposed by Pinpoint.

最后，怀疑该望远镜镜配合机械弯曲芒特附件偶尔增加了额外的错误的指向，导致这些数据的总误差超过11 弧米的Pinpoint施加限制。

The analysis results showed that the strapdown approach will be faced to more error sources with sensor noise and motion disturbance. The simulation results verified this and indicated that the performance of the strapdown approach would not be as efficient as that of the direct approach.3. Analyzing the principle and error model of MEMS QRS gyro for the purpose of practical applications, the paper presented an autoregressive model for the gyro signal by means of time series theory.

应用牛顿力学原理分析了光电稳定跟踪机构的惯量耦合关系和动力学模型，推导了平台单轴伺服回路的控制方程，比较了直接稳定和捷联稳定方案在测量噪声和外部扰动共同作用下的性能特点，仿真结果表明，在同等噪声和扰动条件下，捷联稳定面临更多的误差源，因而最终的稳定精度较难达到直接稳定系统的水平。3。

The method of estimation in paper [7] is to build fitness function by the 2-norm of error matrix directly. For the error matrix is a Toeplitz matrix, a novel fitness function was presented. Then a new method, the real-valued genetic algorithm which is based on genes weights variation independently, is developed in this paper.
