Abstract

Studies of cosmic sources - pulsars require solving complex problems from detection of pulsed radio emission to determination these pulses main parameters. The authors solve these problems by use of hybrid processor with distributed processing: broadband spectral analysis of radiation is performed in analog form in a coherent acousto-optic Fourier processor (conveyor-sliding integral transform), the output of which is additionally compressed in the multi-element photodetector operating in time delay and integration mode (a photodetector is a discrete-analog processor here), a further increase the signal/noise ratio is produced by accumulation of photodetector output data in a digital microprocessor, which also executes control of hybrid processor as a whole. The report shows the results of numerical simulation of the arrangement in MATLAB. Discussed are also the possibilities of using of two-channel acousto-optical interferometric processor to obtain estimates of the parameters of polarized pulsars radio emission.

脉冲星射电发射探测与测量声光电处理器分布式处理

宇宙源脉冲星的研究需要解决从探测脉冲射电发射到确定这些脉冲主要参数的复杂问题。采用混合处理机和分布式处理机解决了这些问题:在相干声光傅立叶处理器(传送带滑动积分变换)中以模拟形式对辐射进行宽带频谱分析，其输出在以时间延迟和集成模式工作的多元件光电探测器中被额外压缩(光电探测器在这里是一个离散模拟处理器)，通过在数字微处理器中积累光电探测器输出数据，进一步增加信噪比。同时对混合处理器进行整体控制。文中给出了在MATLAB中对其进行数值模拟的结果。讨论了利用双通道声光干涉处理机估计极化脉冲星射电发射参数的可能性。
