9404 与采用随机低密度奇偶检验码(low density parity-check,LDPC)码的编码协作方案相比,采用联合设计RA码的系统误码性能更为优越。 With the random low density parity check code (low density parity check, LDPC) code coding collaboration scheme, compared to the joint design of RA code system ber performance is more superior.
9405 防空导弹武器系统效能通常采用ADC(availability,dependability,capability)模型来评定。 Air defense missile weapon system effectiveness is usually adopt the ADC (the availability, dependability and capability) model to assess.
9406 随着装备的发展和对抗复杂性的提升,系统可信度的建模和分析计算越发关键。 With the development of equipment and against complexity, improve system reliability modeling and analysis all the more critical.
9407 通过分析装备本身的功能组成结构,分析系统所有可能的状态及状态转移概率,来建立可信度的求解模型。 Through the analysis of the function structure of the equipment itself, analysis system state and state transition probability of all possible solution model to establish credibility.
9408 并用算例进一步验证了模型,证明了模型的适用性。 By example to further verify the model, prove the applicability of the model.
9409 在部分均匀海杂波环境下,海杂波的瞬时功率波动起伏较大,导致海面目标检测的性能受到影响。 In the part of the uniform sea clutter environment, sea clutter fluctuation of instantaneous power fluctuations, lead to the surface of the target detection performance is affected.
9410 为了减小此影响,引入一个平滑因子以实现对杂波功率的控制,提出了平滑-广义似然比检测器(smooth-generalized likelihood ratio test,S-GLRT)。 ‭In order to reduce the impact, the introduction of a smooth factor in order to realize the control of the clutter power, put forward the smooth - generalized likelihood ratio detector (smooth - generalized likelihood thewire test, S - GLRT).
9411 通过推导S-GLRT的虚警概率表达式,表明其相对于杂波纹理分量的尺度参数具有恒虚警特性。 ‭By deriving the S - GLRT false-alarm probability expressions, show that the relative to the noise ripple of the scale of the principle component parameters with constant false alarm properties.
9412 在不增加计算复杂度的前提下,实验结果表明,在部分均匀的海杂波背景下,S-GLRT优于GLRT。 ‭Under the premise of without increasing computational complexity, the experimental results show that the part of the uniform sea clutter background, S - GLRT is superior to the GLRT. ‭
9413 针对存在频谱混叠的窄带雷达微动信号平动补偿问题,从高阶和低阶频谱混叠两种情况出发,给出了一种平动补偿方法。 In view of the existing spectrum aliasing narrow-band LeiDaWei signal translation compensation, from the high order and low order spectrum aliasing two cases, a translational motion compensation method is presented.
