10076 为应对高频雷达窄带干扰,稀疏信号可将发射能量分配到各离散的"寂静"频带来获得大信干比,但频谱稀疏会引起距离旁瓣抬高。 Narrowband interference in response to the high frequency radar, energy is emitted by a sparse signal can be assigned to each discrete frequency "silence" brings a big letter than done, but the spectrum sparse cause distance sidelobe raise.
10077 由于信干比和旁瓣以冲突形式耦合,在优化设计时需同时考虑,属于多目标优化问题。 ‭Due to dry ratio and sidelobe coupling in the form of conflict, the optimization design needs to consider at the same time, belongs to multi-objective optimization problem.
10078 为此,推导出已知干扰样式下的信干比及积分旁瓣水平的解析表达式,利用梯度迭代算法得到这两个指标加权和的最优解,并遍历权值得到Pareto最优曲线。 ‭Therefore, known interference is deduced under the style of letter dry ratio and the analytical expression of the integral sidelobe level weighted by two indexes which are obtained by gradient iteration algorithm and the optimal solution, and traverse the worth to the Pareto optimal curve.
10079 在仿真中,结合示例利用Pareto最优曲线对不同权重下的波形设计结果进行对比分析,表明该优化方法在实际应用中具有灵活性。 ‭In simulation, combining with the example using the Pareto optimal curve under different weights for comparing with the results of waveform design analysis, show that the optimization method has flexibility in practical application. ‭
10080 微机电系统(micro-electro-mechanic system,MEMS)陀螺仪作为一类新型角速率传感器,其制造和应用过程中不可避免会受到不匹配干扰的影响,即速度项的测量过程中引入各种噪声,降低MEMS陀螺仪的检测精度。 MEMS (micro - company - mechanic system, MEMS) gyroscope as a kind of new type of angular rate sensor, the inevitable in the process of manufacture and application are influenced by the interference does not match, the speed of measurement in the process of introducing all kinds of noise, reduce the detection precision of MEMS gyroscope.
