Jian Yang,Zengtian Chang,Dongchu Su,Chenyong Li,Siwei Luo,Bowei Chang,Lu Qiang +6 more
TL;DR: In this article , the interference between public mobile communication system and S-band radars was investigated, and an applicable interference analysis model was established, the typical frequency parameters of radar and the key parameters of the base station were sorted out, the radiation parameters of mobile terminal (MT) were tested practically, and the interferences of the mobile terminal and MT to radar were calculated.
Simulation Analysis of RBW Parameters of Spectrum Analyzer Based on Convolution Approach
TL;DR: In this article , an economic, RBW arbitrary adjustable, high accuracy equivalent convolution method was applied for the simulation of the RBW parameters of the spectrum analyzer, and evaluated the effect of RBW and filter type on the degree of output spectrum aliasing based on a typical equal-amplitude two-tone signal input.
