Les signaux radar modernes se situent dans un large espace de fréquences. La bande passante de réception du récepteur radar de reconnaissance doit être suffisamment large pour intercepter les signaux radar modernes. Le récepteur pliable Nyquist (NYFR) est une nouvelle architecture de réception à large bande et présente une probabilité d'interception élevée. Les signaux Chirp sont largement utilisés dans les systèmes radar modernes. En raison de sa capacité de réception à large bande, le NYFR recevra plusieurs signaux chirp simultanés. Dans cette lettre, nous proposons un nouvel algorithme d'estimation de paramètres pour les multiples signaux chirp interceptés par NYFR monocanal. Par rapport au NYFR composite, la méthode proposée permet d'économiser des ressources de réception. De plus, l’approche proposée peut estimer les paramètres des signaux chirp même si les sorties NYFR sont soumises à des circonstances de repliement de fréquence. Les résultats de simulation montrent l'efficacité de la méthode proposée.

Abstract: The modern radar signals are in a wide frequency space. The receiving bandwidth of the radar reconnaissance receiver should be wide enough to intercept the modern radar signals. The Nyquist folding receiver (NYFR) is a novel wideband receiving architecture and it has a high intercept probability. Chirp signals are widely used in modern radar system. Because of the wideband receiving ability, the NYFR will receive the concurrent multiple chirp signals. In this letter, we propose a novel parameter estimation algorithm for the multiple chirp signals intercepted by single channel NYFR. Compared with the composite NYFR, the proposed method can save receiving resources. In addition, the proposed approach can estimate the parameters of the chirp signals even the NYFR outputs are under frequency aliasing circumstance. Simulation results show the efficacy of the proposed method.
