Scanning Antenna Array’s False Bearings Identification

In this research we represent the concept of scanning antenna array's false bearings identification method. The method is applicable when groups of antenna elements are combined into one transceiver channel or (and) the inter-element distance of the channels is large enough for additional filling. Grating lobes of the antenna radiation pattern appear during scanning, which are absent in the radiation pattern without scanning. The difference between scanning and non-scanning radiation patterns is estimated using this method. The method can be used in multichannel digital antenna arrays (MIMO radar) and APAA.
