The sidelobe contaminatin index is determined by using variational methods . coordinate conversion with linear interpolation 运用变分法来确定旁瓣污染指数，运用线性插值进行坐标转换。
The sidelobes are controlled by introducing a large number of interfering signal at many angles throughout the sidelobe region 本章还利用人工加载干扰的方法，提出了一种低旁瓣电平波束合成算法。
And target signal cancellation is a serious problem . many signal processing techniques have been proposed to avoid signal cancellation 因此，在宽带旁瓣对消器中目标信号被消除是一个非常严重的问题。
The thesis brings forward the scheme that combines polarization filter and side lobe canceller to improve the anti - jamming ability of radar 论文提出将极化滤波与旁瓣对消结合起来提高雷达抗干扰性能的方法。
There exist wide sidelobes around correlationpeaks of song correlation and mc , which would affect the strict locating of wantedobject seriously Song相关器和mc的相关峰还存在着较宽的旁瓣,严重影响目标定位。
The main results are as follows : 1 . a method to design low sidelobe fsk / psk radar signals using genetic algorithm . 2 综上所述,本文研究的内容主要有: 1 .研究了一种用遗传算法设计低旁瓣fsk / psk雷达信号的方法。
The mainlobe - sidelobe characters of the pn codes are also discussed when modulated by the signals and carrier - doppler exsists in chapter 3 本文第三章分析了存在载波多普勒、有符号调制时的周期伪随机序列的主旁瓣特性。
For lfm signal , we demonstrate the method of employing hamming weighting , spectrum correcting and phase modulation distortion 对线性调频信号的旁瓣抑制介绍了经典海明窗加权处理方法、频谱修正以及相位预矫正几种方法。
