Abstract
Description
(1)本発明はテンソルでコプライム平面の実際の受信信号を表示し、従来の方法と異なり二次元空間情報をベクトル化して特徴付け、かつスナップショット情報を平均して二次統計量を得て、本発明は各サンプリングスナップショット信号を第三次元で重ね合わせ、かつ四次元空間情報を含む二次相互相関テンソルを利用して空間スペクトル推定を行い、コプライム平面アレーの実際の入射信号の多次元空間構造情報を保留する。
(2)本発明はバーチャルドメイン等価信号のテンソル統計量分析によりバーチャルドメイン信号のサブ空間分類構想を構築し、テンソル空間スペクトルの構造に理論的な基礎を提供し、それによりコプライム平面アレー信号のミスマッチの問題を解決し、ナイキストマッチング条件に合致するバーチャルドメインテンソル空間スペクトル構造を実現する。
(3)本発明はテンソルCANDECOMP/PARACFAC分解及び高次特異値分解の方式を採用してバーチャルドメイン信号の四次自己相関テンソルに対して多次元特徴抽出を行い、それによりバーチャルドメインモデルと信号、ノイズサブ空間との間の関係を確立し、高精度、高分解能のテンソル空間スペクトルを実現するために基礎を提供する。
