摘要
低截获概率(LPI)雷达及捷变频雷达的出现,给传统的被动雷达导引头接收机带来了极大的挑战。为了适应宽带信号的接收,使其具有对同时到达的多部雷达信号的处理能力,本课题围绕数字信道化接收机及其在被动雷达导引头中的应用展开研究。主要研究了数字信道化的高效结构、动态信道化接收技术以及信道化后续处理技术。以工程应用为背景,设计并实现了一套数字信道化接收机,并对其性能进行了测试及分析。
     在均匀数字信道化方面,分析了复信号和实信号频带划分方式,并从滤波器组低通实现结构出发,推导了一种具有普遍性的多相滤波结构。针对不同的频带划分方式,分别推导并给出了复信号在不同条件下(临界抽取或非临界抽取、偶型排列或奇型排列)的各种信道化高效结构模型以及实信号对应不同频带划分下的信道化结构模型。在此基础上,提出了一种实信号无混叠无盲区的信道化高效结构和一种基于加权重叠相加结构的信道化高效结构,并对各信道化高效结构的运算量进行了对比分析。
     针对数字信道化技术在被动雷达导引头中的应用,提出了一种提高信号分选通道灵敏度的数字信道化接收方案,同时为信号分选提供了新的分选参数(相位差信息)。讨论了实信号偶型排列信道化结构中信道0存在的仅有实部,而无虚部输出的问题,并提出了一种基于希尔伯特变换的I、Q信道产生方法,解决了信道0不能直接用于参数分析的问题。并对数字信道化高效结构的实现方法进行了研究。
     在动态信道化接收方面,根据信号重构理论,推导了并给出了基于DFT滤波器组的高效动态信道化结构和基于WOLA的高效动态信道化结构。上述两种结构均可以实现非均匀信道划分,根据信道检测的结果实现动态信道化接收,解决了宽带信号跨信道的问题。
     信道化后续处理方面,采用了CORDIC算法实现了信号包络和瞬时相位提取,并采用相位差分算法实现了频率测量。采用相位干涉仪测向原理,分别提取两路中频信号的瞬时相位并做差、解卷绕后得到相位差信息。针对均匀信道化子带信道带宽较宽,可能存在多信号问题,采用了FFT谱分析的方法对各子带信道进行谱分析,并对其FPGA实现的资源占用情况进行了评估。
     在系统实现方面,采用了国家半导体公司的高速ADC08D1000和ALTERA公司的FPGA芯片设计并实现了一套数字信道化接收机。对系统各项功能和技术指标进行了详细测试,并对测试结果进行了分析,提出了一些改进意见。
LPI radar and frequency agility radar have brought a great challege for tranditonal receiver of passive radar seeker. In order to receive wideband signals and process multiple simultaneous signals, application of digital channelized receiver in passive radar seeker was studied in this dissertation. The efficient architectures of digital channelized receiver, dynamic channelized receiving technology and channelized subsequent processing technology were primarily researched. A set of digital channelized receiver was designed and realized based on engineering application and the performance of the digital channelized receiver was tested and analyzed.
     In respect of uniform digital channelized, the frequency band division methods of complex signal and real signal were analyzed and an universal polyphase filter architecture was deduced form low pass filter architecture. According to different frequency band divisions, the various complex signal efficient channelized architectures and real signal efficient channelized architectures were given in different conditions that are critical decimation or non-critical decimation, even alignment or odd alignment. A real signal efficient channelized architecture based on non-aliasing and non-blind area and an efficient channelized architecture based on WOLA were proposed. The calculations of various efficient channelized architectures were compared and analyzed.
     A digital channelized receiving method, which improved sensitivity of signal sorting channel and provided new sorting parameter, was proposed according to digital channelized application in passive radar seeker. A problem that the outputs of 0th channel have real part and have not image part in real signal even alignment architecture was discussed. A kind of I and Q channels generation method based on Hilbert transform was proposed in order to realize parameter analysis of 0th channel. The implementation method of digital channelized efficient architecture was studied.
     In respect of dynamic channelized receiving, the efficient dynamic channelized architectures based on DFT and based on WOLA were deduced based on signal reconstruction theory. The two architectures can realize non-uniform channel division and dynamic channelized receiving by estimation of channel to solve the cross-channels problem for wide band signals.
     In respect of channelized subsequent processing, the CORDIC algorithm was adopted to extract signal envelope and instantaneous phase and the phase difference algorithm was adopted to realize frequency measurement. The phase difference was gotten by instantaneous phases subtracting of two intermediate frequency signals and phase-unwrapping. As sub-channels were wide, it is possible to exist multiple signals in sub-channels. The method of FFT spectral analysis was adopted and the resource occupying of FPGA was evaluated.
     In respect of system implementation, the high-speed ADC08D1000 of National Semiconductor and the FPGA of ALTERA were adopted to realize a set of digital channelized receiver. The various functions and technical specifications were tested and analyzed in detail and some improved suggestions were proposed.
