Stepped frequency chirp signal imaging radar jamming using two-dimensional nonperiodic phase modulation Research Article

Qihua WU, Feng ZHAO, Tiehua ZHAO, Xiaobin LIU, Junjie WANG, Shunping XIAO

Frontiers of Information Technology & Electronic Engineering 2023, Volume 24, Issue 3,   Pages 433-446 doi: 10.1631/FITEE.2200298

Abstract: obtains high-resolution radar images by synthesizing multiple narrowband chirp pulses. It has been one of the most commonly used waveforms due to its lower demand for radar instant bandwidth. In this paper, we propose a method using two-dimensional against imaging radar. Using the unique property of , the proposed method can generate high-level sidelobes that perform as a special blanket jamming along both the range and azimuth directions and make the target unrecognizable. Then, the influence of different modulation parameters, such as the code width and duty ratio, are further discussed. Based on this, the corresponding parameter design principles are presented. Finally, the validity of the proposed method is demonstrated by the Yake-42 plane data simulation and measured unmanned aerial vehicle data experiment.

Frontiers of Mechanical Engineering 2012, Volume 7, Issue 3,   Pages 322-328 doi: 10.1007/s11465-012-0312-9

Abstract:

A sine generation method that the different frequent sine signals can be generated by the different Pulse-Width Modulation (PWM) signals generated by Field-Programmable Gate Array (FPGA) through low-pass filter of fixed parameters was proposed. The method just takes a few FPGA resources and was proved feasible by the theory. The experiment results and theory analysis tally.
