amplitude
Examples
- This paper is mainly about land clutter and sea clutter . it meanly introduced scatter character , radar echo signal range , and power spectrum model . in the end , a hardware realization of producing a specified power spectrum is given
本文主要研究了地、海杂波的散射特性、回波幅度特性和频谱分布模型，并且给出了一种硬件实现产生具有一定频谱特性的杂波的方案。 - Motion errors are given first , and then theoretical analysis , simulation result show affections caused by 3 kinds of typical motion errors both on the doppler and the image . last the phase error criterions are given . 4
4 .研究了机载双站sar中偏航、俯仰和横滚三种姿态误差对回波多普勒频率和雷达成像的影响,并分析研究了天线指向误差对回波幅度的影响,最后通过仿真实验证明了研究的正确性。 - At this moment , both the direct signal and the reflected one impinge into the array , and make the amplitude and phase of the echo change , which cannot be separated from the direct one , thus cause server errors of elevation ’ s estimation , even the failure of tracking
此时直达信号与反射信号同时进入天线,造成回波幅度与相位的变化,并且这种变化不能从直达信号中分离出来,从而造成目标仰角估计的严重误差,甚至引起跟踪的失效。 - The way reduces the error . this paper also particularizes the prime parameter of the echo - - radar cross section ( rcs ) which is influenced by many factors . considering the fluctuation of rcs and the modulation by the radar antenna , the paper contains both slow and quick fluctuating targets
两种回波的仿真数据表明：仿真结果与理论模型的结论符合很好，能够满足运动目标回波幅度分布特性的要求；并且在多数情况下，雷达探测到的目标都是慢起伏目标。
