A Method for Complex Impedance Determining by the Reflection Coefficient Magnitude-Only Measurement
A simple but accurate method for determining the complex impedance of an arbitrary load is described. This method does not require the use of a vector network analyzer or phase measurement. Two measurements of the reflection ...
On the development of a universal two-channel sensitive digital sensor for recording seismic vibrations
This article discusses the development of twochannel sensitive sensors for recording seismic vibrations. The influence of the instability of the element base in the implementation of sensor data using analog amplifiers and ...
Simple Pre-Steering Constraints for Wideband LCMV-beamformer
The LCMV-beamformers are widely used in many applications but to steer array pattern in some direction we need to use phase shifters or additional delay lines for presteering. In this paper, we introduce simple constraints ...
Multiband Three-Layer GNSS Microstrip Antenna
There are various receiving antennas of satellite radio navigation systems. As a rule, the qualitative polarization characteristics (axial ratio) are achieved by efficiency degradation or frequency ranges decreasing. In ...
The Quality Indicators of the Processing Procedure for a Spread Spectrum Signal Using Statistical Modeling Investigation
In this paper statistical modeling techniques to assess the accuracy of determining the temporal position of spread spectrum signal is shown. The results of the statistical modeling are presented: RMS of errors in determining ...
