BPSK-signals reception quality depends on the quality of the signal processing. BPSK-modulated codes reception quality depends on the quality of the correlation functions. RF frontend distortions leads to efficiency of the signal processing degrading. RF frontend non-optimal filtering, noise and dynamic range limiting has significant impact on the signal processing quality. In this research simulation...
In the article electromagnetic compatibility (EMC) tests are discussed. These tests include radiated susceptibility (RS) tests. An electronic equipment of small space vehicles is to be subjected to RS tests. A four-wire transmission line is used as an electric field source. It was applied for EMC tests for the first time. Homogeneity of the electric field in the source was studied. It is presented...
Fast method of inner calibration of individual channel of active phased antenna arrays (APAA) has been introduced earlier. This method can be used for measuring complex amplitude characteristics of individual channels of both receive and transmit APAA using single measurement procedure. However, this method returns complex amplitude characteristics only at single carrier frequency; for wideband systems...
Advanced method of inner calibration of individual receive modules of active phased antenna arrays (APAA) in synthetic aperture radar (SAR) is discussed. This method allows fast and accuracy amplitude and phase characterization of every receive modules and uses pseudo-noise sequences as core of calibrating sequences system. Decorrelation method of cancelling mutual interference using simple matrix...
