入射信号 meaning in English

incident signal

Equally objectionable is the fact that saturation by spontaneous emission reduces the gain exercised by an incoming signal .
同样不利的事实是，自发辐射引起的饱和减少了入射信号所能获得的增益。
However , when the system sample number and the number of antenna array elements are finite , or snr is low and the incident signals are correlated or coherent , the performance of the algorithm sharply decreases and the algorithm even becomes invalid
但是当系统样本数、天线阵元数有限,信噪比较低以及入射信号为相关或相干信号时,算法性能急剧下降甚至失效。
From three - wave coupling equations , the optimal crystal length , conversion efficiency and parametric light pulse width are computed numerically when clbo is used in picosecond optical parametric amplification . the results present that clbo are suited for optical parametric amplification in short wave band . in order to get higher conversion efficiency , the crystal length should be optimized according to the intensities of pump and signal waves
从三波耦合方程出发，对clbo用于皮秒级光参量放大时，最佳晶体长度、转换效率和参量光的脉冲宽度进行了理论分析和数值模拟，结果表明clbo晶体适合在短波范围作光参量放大，为达到高的转换效率和窄脉宽的信号光输出，泵浦光和初始入射信号光的强度应根据晶体长度取最优化值。
