Abstract
Description
図1は、実施の形態1に係るアクティブフェーズドアレーアンテナを示すブロック図である。複数の受信モジュール1a,1bは、複数のアンテナ2a,2bからそれぞれ信号を受信する。合成器3は、複数の受信モジュール1a,1bの出力信号を合成する。AD変換器4は、合成器3により合成された信号をデジタルデータに変換する。
図6は、実施の形態2に係るアクティブフェーズドアレーアンテナを示すブロック図である。本実施の形態では、第1のサンプルホールド回路7a,7bは、搬送波帯域の信号を直接サンプルホールドして、周波数変換とサンプルホールドを同時に行なう。FIRフィルタ17a,17bは、それぞれ第1のサンプルホールド回路7a,7bの出力信号のサンプリングレートをレート変換するレート変換部であり、サンプリングレートを下げながら移相の線形性を保ったまま不要信号を除去する。
