Compared with the infrared focal plane array (IRFPA) based on amorphous silicon (α-Si), IRFPA based on vanadium oxide (VOx) has the advantages of big temperature coefficient, low noise and so on. Therefore, it is believed that VOx IRFPA has important application in both military and civil field. In this paper, the designs of driving module and signal processing module of VOx IRFPA are proposed. Firstly,...
We have developed a sequential beamspace method for high resolution direction of arrival (DOA) estimation. Beamspace MUSIC and element space MUSIC DOA estimation algorithms have been implemented to utilize an 8 element uniform circular array operating at 5.8 GHz. The simulation and initial lab results show that the proposed method can achieve good accuracy once it is properly sychronized. In addition,...
This paper describes our design of a compact and efficient beamspace direction of arrival (DOA) estimation and beamspace beamforming device. The robust functionality includes high resolution RF emitter DOA estimation and beamforming in a noisy environment with strong interference. Simulations for beamspace DOA estimation using beamspace MUSIC and beamspace Capon methods are presented in conjunction...
