Generation and calibration techniques for high-precision narrow-pulse signals

Aiming at the technical limitations of existing narrow-pulse modulated signal generation methods for ultra-wideband radar target simulators, such as low accuracy, poor stability, and insufficient modulation flexibility, this paper proposes a high-precision, high-stability, and flexibly controlled narrow-pulse modulated signal generation and calibration method. Based on digital IQ modulation and software-defined radio technology, the method balances data generation quality and transmission efficiency while fully considering hardware capabilities such as sampling rate, storage and transmission capacity, signal processing capability, and synchronization and triggering functionality. The proposed method aims to meet the complex signal processing requirements in modern radar and communication fields, addressing the challenges of ultra-wideband narrow-pulse modulated signal generation and measurement traceability. Experimental verification demonstrates that the scheme features strong scalability and ease of implementation, providing effective methods and tools for narrow-pulse signal generation and calibration in radar, communication systems.
