In passive radar, the direct and multipath interference in echo channel must be suppressed before target detection. As the bandwidth of the digital television(DTV) signal is quite broad, when target detection is performed utilizing DTV signal, the inconsistency of the reference channel and the echo channel will leads to the degradation of the cancellation gain and radar operation range. To solve this...
The primary mission of the PSSC Testbed is to provide space flight data on two types of advanced solar cells, XTJ and ZTJ, produced by the two U.S. solar cell manufacturers, Spectrolab and Emcore, respectively. The PSSC Testbed flight data confirmed that the picosatellite can be used for measuring l-V characteristics of solar cells. Continuing monitoring of the l-V measurement will allow determining...
Results of radiation effects and annealing studies are presented for amorphous silicon solar cells from three manufacturers. Data scale well with ionizing dose in many cases for proton, x-ray, and electron irradiation. Significant long-term annealing occurs at room temperature. Results for small-area diodes are in reasonable agreement with findings for monolithic modules. Damage mechanisms in irradiated...
This paper aims to evaluate the curative effects of low-intensity laser external radiotherapy through thermal texture mapping (TTM) technology. The influences of 30 min nasal cavity irradiation of semiconductor laser (650 nm, 5 mW, continuous wave) on microcirculation were investigated through TTM. At the same time, with the aid of TTM, the influences of the irradiation on the whole body thermal balances...
