최신 레이더 신호는 넓은 주파수 공간에 있습니다. 레이더 정찰 수신기의 수신 대역폭은 최신 레이더 신호를 차단할 수 있을 만큼 넓어야 합니다. NYFR(Nyquist Folding Receiver)은 새로운 광대역 수신 아키텍처이며 높은 차단 확률을 가지고 있습니다. Chirp 신호는 현대 레이더 시스템에서 널리 사용됩니다. 광대역 수신 기능으로 인해 NYFR은 동시 다중 처프 신호를 수신합니다. 이 편지에서 우리는 단일 채널 NYFR에 의해 차단된 다중 처프 신호에 대한 새로운 매개변수 추정 알고리즘을 제안합니다. 제안된 방법은 복합 NYFR과 비교하여 수신 자원을 절약할 수 있다. 또한 제안된 접근 방식은 NYFR 출력이 주파수 앨리어싱 상황에서도 처프 신호의 매개변수를 추정할 수 있습니다. 시뮬레이션 결과는 제안된 방법의 유효성을 보여줍니다.

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.
