A direction finding algorithm of two-dimensional circular array phase interferometer with three antennas is introduced. The expressions of pitch angle and azimuth are given, and they can be extended to two-dimensional circular array phase interferometer with more antennas. We also analyze the factors that caused the error and propose a correction method using known source to solve the problem of phase uncertainty of sensorarray. Finally, Matlab is used to prove the feasibility of the direction finding algorithm of three circular antennas array and its correction method. The simulation results show the algorithm is effective and it can meet the requirements of accuracy. When working at the circumstance of single signal source, the methods we proposed is very simple and fast to implement compared to other algorithms, such as the MUSIC and the ESPRIT, though the accuracy is not better than them. And it can be used at real-time signalprocessing system easily, which is difficult for MUSIC and ESPRIT.
In this paper, non standard deterministic parameters estimation is considered, i.e. the situation where the probability density function (p.d.f.) parameterized by unknown deterministic parameters results from the marg...

The paper. is devoted to the description and practical verification of a new CCD linear image sensor control method. This method is used for inherent signal preprocessing or processing in the CCD linear image sensor. This new method is suitable for a movement compensation, an one-frame filtration or a two-frame filtration. Because of the similarity between the Non-Recursive Digital Filter with Finite Impulse Response (NRDF FIR) and the new mode it was named FIR mode. Conclusions and hints applicable for operation of CCD image sensor in FIR mode are also included in the paper.
