摘要
本文阐述了天线方向图测量的原理,利用正弦波信号加噪声的包络概密度函数,导出了系统信噪比对旁瓣电平影响的误差修正公式.给出了数值修正曲线,并用实验结果验证了理论计算的正确性.
The principle of antenna pattern measurement is related simply. Error correction formulate of effect of system signal- to-noise ratios on sidelobe level is derived using the envelope probability density function of asinusoidal wave signal plus noise. Correction curve of numerical value is given, the experiment results ale reported to verify the correctness of theory calculation.
