54987 理论分析了在噪声环境中,所提方法测相精度高于全相位FFT测相法的原因。 Theoretical analysis in the noise environment, the proposed method of phase measurement precision is higher than all phase FFT phase measurement method.
54988 仿真实验表明,在信噪比不太低的场合,双子段测相法的相位估计方差处于全相位FFT估计法和两参数克拉美罗限之间,因而具有广泛应用前景。 Simulation results show that the SNR is not too low, the twin section measuring method of phase estimation variance in full FFT phase estimation method and the ROM limit between two parameters, Latin America, which has wide application prospect.
54989 进行软件可靠性评估主要通过构建软件可靠性模型实现。 Software reliability assessment is mainly through to build software reliability model.
54990 软件可靠性模型通常给出被检出的故障可以立即被排除,并且不会有新的故障被引入的假设,这与实际的检错过程是不相符的。 Software reliability model usually was fault detection can be ruled out, immediately and will not be introduced a new fault assumption, which are not in accordance with the actual process of error detection.
54991 针对以上假设条件,提出了一种新的软件可靠性增长模型。 In view of the above assumptions, this paper proposes a new software reliability growth model.
54992 该模型将软件的检错过程和排错过程作为两个独立的非齐次泊松过程分别进行建模,并将软件中存在的故障数看作是一个变化的函数,该函数包括软件中初始故障及引入的故障。 The model error detection process of the software and the debugging process as two independent non-homogeneous poisson process modeling, respectively, and the software fault existing in the number of changes as a function, the function including initial fault and the introduction of faults in the software.
54993 在两个数据集上进行相应实验证明,较之其他模型,新建模型的拟合和预测效果更好。 Corresponding experiments on two data sets show that, compared with other models, the new model fitting and forecast effect is better.
54994 以反导作战时红外预警卫星对地监视覆盖区域计算为需求,结合卫星平台和星载相机的特点,运用点集间投影和映射的思想,首先推导了地球同步轨道卫星对地进行圆锥-旋转扫描与推扫时的覆盖区域模型,运用坐标转换方法,进一步建立了低轨卫星对地扫描覆盖区域模型;提出了一种地球同步轨道卫星对地进行凝视覆盖的新工作模式; To anti-missile combat infrared early warning satellite ground surveillance coverage calculation for requirements, combining with the characteristics of satellite platform and spaceborne camera, based on the idea of projection and mapping between point set, first of all, the earth synchronous orbit satellite is deduced to cone - rotating scanning and push to sweep the coverage model, using coordinate transformation method, further establish the Leo satellite on scanning the coverage model;A geostationary satellites in orbit to stare at to cover new work mode;Limb covering the decision condition is given.
54995 给出了临边覆盖的判定条件。仿真实例表明,该模型能有效计算高低轨红外预警卫星对地监视覆盖区域,能为预警卫星探测与跟踪弹道目标提供有力的技术支撑。 Simulation examples show that the model can effectively calculate the high infrared early-warning satellites that orbit earth ground surveillance coverage, can provide early warning satellite ballistic target detection and tracking with powerful technical support.
