1053 并且传输损耗与大气折射率结构常数间的相关系数均大于 0.7,表明了对流层散射传输损耗与大气折射率结构常数之间较强的相关性。 On the other hand, the correlation coefficients between the transmis-sion loss and the structure constant of the refractive index are all greater than 0. 7.
1054 这种对流层散射与大气折射率结构常数之间的相关性对于对流层散射传输的机理和建模研究都有重要意义。 All of these show that there is indeed astrong correlation between troposcatter transmission loss and structure constant of the refractive index, and this correlation is of great value for the investigation of the mechanism and modeling on troposcatter transmission.
1055 端射阵天线是指波束指向垂直于阵列法线方向的一类特殊雷达天线, End-fire array antenna is a kind of special radar antenna with beam pointing perpendicular to the normal di-rection of the array.
1056 由于其具有低剖面和定向辐射特性,因而特别适合用于机载雷达的补盲。 Because of its low profile and directional radiation characteristics, it is especially suitable for blind com-pensation of airborne radar.
1057 由于端射阵通常呈前视放置,因而与传统前视侧射阵机载雷达一样,不可避免地要面临杂波的距离非平稳问题。 As end-fire array is usually placed forward-looking, it inevitably faces the problem of non-sta-tionary clutter which just likes traditional forward-look side-fire array.
1058 本文基于端射阵机载雷达杂波谱特性,提出了一种距离模糊下端射阵近程杂波补偿新方法。 Based on the clutter spectrum characteristics of end-fire array airborne radar, a novel short-range non-stationary clutter compensation method for end-fire array with range ambi-guity is proposed in this paper.
1059 该方法以最远可检测距离单元为参考单元并增加了动目标约束保护条件,克服了存在距离模糊时基于杂波谱配准( Registration-Based Compensation,RBC) 原理的传统补偿方法存在的目标相消以及计算量大的问题; The farthest detectable range unit is taken as the reference unit and the constraint protectioncondition is added to the moving target in this method, which overcomes the disadvantage of target cancellation and largecomputation of the traditional compensation method based on RBC( Registration-Based Compensation) principle with range ambiguity.
1060 同时针对可能存在的目标约束失配问题,进一步提出了基于虚拟波束的扩展补偿方法。 At the same time, aiming at the problem of the target constraint mismatch, an extended compensation method based on virtual beam is proposed.
1061 计算机仿真结果验证了本文方法的有效性。 The computer simulation results verify the effectiveness of the proposed method.
1062 在谐振极软开关逆变器辅助电路的换流过程中,为避免剩磁通的累积导致变压器铁心饱和,提出了一种变压器辅助换流的三相节能型谐振极逆变器的拓扑结构, In the commutation process of auxiliary circuit in the resonant pole soft-switching inverter, the accumulation of remanence can lead to saturation of transformer core. To avoid this case, the article proposes a novel topology of three-phaseenergy-saving resonant pole inverter with transformer-assisted commutation.
