A Study on Transmitting Frequency Spectrum Control Technology of Digital T/R Modules
The number of radar,communication device and other radio equipment in various frequency bands integrated on a single platform of modern weapons is increasing,and the transmitting signals are developing to the direction of high power and ul-tral-wideband.The transmitting frequency spectrum between radar and other equipment overlaps seriously,leading to serious elec-tromagnetic interference problems between different equipments.In this paper,the electromagnetic interference problems between transmitting and receiving signals of different radio equipments are analyzed,and the generation mechanism and improvement meth-od of the out-of-band spectrum component of digital T/R module pulse transmission are discussed.The specific spectrum control measures are proposed,and experimental verification is conducted on a certain radar digital T/R module,proving the effectiveness of the proposed spectrum control method.
