WebThis work proposes a technique based on the Eulerian circuit for generating a waveform sequence starting from a reduced number of distinct cyclically shifted chirps that can be effectively exploited for waveform-encoded SAR. WebIn this work, we theoretically analyze the effect of the phase noise on the sensing performance and use a Lorentzian filter to mitigate the impact of the laser phase noise. Compared to the raw signal, the proposed method improves the sensing accuracy by approximately 9 dB at the 22-km position. churchfield school highbridge
