By describing a model of binary sequential detector realized on a computer, this paper systematically discusses the questions which are unavoidable in implementing a sequential detector for phased-array radar. The efficiency of sequential detection (two steps) is evaluated with retransmitting probability of beam-pointing. After obtaining the operating characteristics of the sequential detector, the relations among the retransmitting probability of beam-pointing, detectable signal-to-noise ratio and a detection threshold (or a quantization threshold) are quantitatively described, and the guideline for the rational use of radar's energy is offered. Comparing the detection quality of sequential detection with that of density detection, the extent of improvement made by sequential detection for a radar is given. If the value of detection threshold (or quantization threshold) for the radar is properly selected, the sequential detection can improve the tracking ability by more than 3.4dB for the several detectors described in this paper, with a signal-to-noise ratio loss of 1.6dB only.

本文通过在计算机上实现一个二进量化序列法检测模型,讨论了相控阵雷达序列检测器在工程实现时的若干问题。对常用的二步序列法检测,用波束位置补照概率来衡量其检测效果。所建立的检测器工作曲线,定量地描述了波束位置补照概率、检测信噪比与检测门限(或量化门限)的关系,为合理使用雷达能量提供依据。文中比较了二进量化二步序列法与密度法的检测性能。合理选择检测门限(或量化门限),对于文中列举的几个检测器,能够仅以1.6dB的信噪比损失,使雷达的跟踪能力提高3.4dB以上。

A memoryless grouped-data robust sequential detection procedure is proposed. Its robustness including false alarm probability, detection probability and average sample number is demonstrated and its asymptotic performance is discussed. Finally, the performance curves in small sample sizes are given for the p-point distribution class. The detector exhibits simplicity in structure and retains sample-efficiency of sequential detector.

The sequential detecting of received symbol sequences which are transmitted over a Homogeneous Random Time-Varying Channel(HRTVC)is discussed.Then lower and upper bounds on the bit error probability of sequential detectors with different mismatch are obtained.These bounds are rather tight when the SNR and the smbols that interfere with each other are large.We find that there exists an optimum transmis- sion rate which makes the bit error probability minimum for a given mismatch and a given SNR,the more severe the mismatch,the lower the optimum transmission rate. If there were no mismatch,the intersymbol interference(ISI)would never limite the transmission rate,the more severe the ISI,the better the system performance,and in the limiting case,when the support of the ISI became infinite,the bit error pro- bability would approach to that of the AWGN channel.

本文介绍了应用于齐次性随机时变符号干扰信道中的序列检测枝术,求出了不同失配时,序列检测器比特差错率的上下界。在信噪比较高、符号干扰严重时,上下界相当紧密。在失配与信噪比一定时,存在一个使比特差错率最小的最佳传信率。失配越小,最佳传信率越高。在无失配时,符号干扰再也不是限制传信率的因素,符号干扰越严重,系统性能反而越好。在符号干扰无限严重时,系统反而被改造成恒参高斯信道了。
