A method for equalizing frequency responses of the adaptive antenna array channels is shown. This method does not require a reference signal or some additional antennas. Equalizing is performed on the received signal (like interference signal).
The simulation and experimental results of quadrupole antenna with four power points to create a right-hand circular polarization with respect to the systems IRNSS/GLONASS/GPS were presented.
The expression for power pattern of the antenna array with any layout at random errors in the complex weights is obtained. The expression for directivity evaluating is given. Interference suppression performance for adaptive arrays with random errors is shown.
The principles of making radiation pattern zeros in the given direction are illuminated. Radiation patterns for the cases of interference coming from different directions and amplitude-phase distributions corresponding to these patterns are given.
Set the date range to filter the displayed results. You can set a starting date, ending date or both. You can enter the dates manually or choose them from the calendar.
