去调频宽带LFM信号二次距离压缩合成孔径雷达SRCBased on the analysis of the time and frequency domain character of the de-chirped broadband LFM signal, this paper presents the SRC imaging method of SAR with de-chirped LFM signal. In comparison with the RD and SRC method of normal LFM signal ...
1.An interferometric system, comprising:a broadband source;an interferometer between said broadband source and an object; anda detector circuit;wherein a signal from said source is divided into a signal arm and a reference arm of said interferometer, light in the signal arm being reflected back ...
This paper mainly analyses the structure of LFM-SAR system, the theory of de-chirped signal and the process of Range Doppler Algorithm (RDA) in detail. At last, the simulation results prove that LFM-CW SAR has a good spatial resolution....
parameters change, envelope area of a reflection spectrum used for sensing optical chirped-grating changes accordingly; the demodulation part is strength type demodulating equipment which is mainly composed of a broadband light source, a demodulation light path, an O/E and signal processing circuit. ...
The laser system and method further include a pulse shaping unit measuring a spectral phase across the recompressed pulse and further adjusting the deviation of the measured spectral phase from that of the TL pulse by generating a corrective signal. The corrective signal is applied to the array ...
This approach provides very high frequency microwave signal with lowest possible phase noise. OEO has been designed with miscellaneous architecture by introducing different optical dispersive components such as optical fiber, chirped fiber Bragg grating, polarization modulator,...
By exploiting broadband electronics, and thanks to its high signal-to-noise ratio, this technique allows the acquisition, in a single-shot, of frequency-calibrated, mid-infrared molecular spectra spanning up to 100 GHz and beyond, which is particularly attractive for fast, active remote sensing ...
PROBLEM TO BE SOLVED: To efficiently manufacture the long chirped grating optical fiber by using the beat signal, outputted by ring laser gyro which rotates concentrically at the same speed with the spool for the optical fiber, as an irradiation command signal to a laser light irradiation device...
