The main disadvantage of satellite radio navigation systems is their low noise immunity. This is because the orbit of navigation satellites is 20 000 km above ground level, and the navigation signal from satellites, is extremely low. Apply-ing the optimal methods of signal processing, however, manages to hold reasonably accurate navigational dimension. However, in the case of complex electromagnetic environment navigation signals are easily suppressed. Interference sources can be communication systems, radar, etc. Especially the problem of navigation signal suppression manifests around airports. In recent years, the problem of noise immunity of radio equipment has received much attention. Method synthesis of amplitude-phase distribution of hybrid-mirror antenna, providing formation of contour service area and failures of directional pattern towards at least three sources of an interfering signal is suggested. The method ensures the formation of failures in the chart orientation to minus 45–50 DB at signal level not more than 1 DB for corner signal timing and interference not less than 0.15 of the width of the NAM in the main petal days. Under the situation of interference in the direction of reducing side lobe, useful signal does not occur. In addition, the developed method pro-vides an accelerated adaptation to jamming conditions of a choice of pre-calculated variants of amplitude distribution of antenna array of the most close to the optimal, mainly petal pattern. Adaptation time is reduced by 25 %, taking into account the performance of modern shifters, the speed of which is comparable with the time of work of Adaptive algo-rithms. To speed up calculation of amplitude-phase distribution of the target function was limited to a set of points specified programmatically that allows the 5 times reduction of time of synthesis in comparison with the classic gradi-ent method.
Keywords: Adaptive antenna array, adaptation algorithm, multi-beam antenna, hybrid-reflector antenna.
