Effect of non-uniform illumination on performance of solar thermoelectric generators

Ershuai YIN, Qiang LI, Yimin XUAN

Frontiers in Energy 2018, Volume 12, Issue 2,   Pages 239-248 doi: 10.1007/s11708-018-0533-7

Abstract: The non-uniform illumination caused by the optical concentrator may affect the performance of solar thermoelectricThe influences of non-uniform illumination on the temperature distribution, the voltage distribution,generators with 32, 18 and 8 pairs of thermocouples are compared to investigate their capability under non-uniformThe non-uniform solar illumination will weaken the capability of the TE generator, and the maximum outputReducing the number of the thermoelectric legs for non-uniform solar illumination can greatly increase

Efficient coherent detection of maneuvering targets based on location rotation transform and non-uniform Research Articles

Ke Jin, Tao Lai, Yan-li Qi, Jie Huang, Yong-jun Zhao,jinke_xd@outlook.com

Frontiers of Information Technology & Electronic Engineering 2020, Volume 21, Issue 8,   Pages 1251-1266 doi: 10.1631/FITEE.1900272

Abstract: Long-term can remarkably improve the ability of detection and motion of radar for s. However, the linear range migration, quadratic range migration (QRM), and Doppler frequency migration within the coherent processing interval seriously degrade the detection and estimation performance. Therefore, an efficient and noise-resistant method based on and is proposed. QRM is corrected by the second-order keystone transform. Using the relationship between the rotation angle and Doppler frequency, a novel phase compensation function is constructed. Motion parameters can be rapidly estimated by LRT and NuFFT. Compared with several representative algorithms, the proposed method achieves a nearly ideal detection performance with low computational cost. Finally, experiments based on measured radar data are conducted to verify the proposed algorithm.
