    • Robust methods are developed to provide bounds and probability distributions for the locations of objects as well as for associated variables that affect the accuracy of the location such as the positions of stations, the measurements, and errors in the speed of signal propagation. Realistic prior probability distributions of pertinent variables are permitted for the locations of stations, the speed of signal propagation, and errors in measurements. Bounds and probability distributions can be obtained without making any assumption of linearity. The sequential methods used for location are applicable in other applications in which a function of the probability distribution is desired for variables that are related to measurements.

    • A detection problem is introduced for a source of some bandwidth and unknown waveform and emission time in the presence of noise of uncertain variance. The signal travels to the receivers along paths whose delays may be unknown. Using a new receiver called a “matched-lag filter,” the presence or absence of the signal is estimated from the auto- and cross-correlation functions of the received signals. The use of correlation functions provides the first stage of gain in signal-to-noise ratio, like a matched filter, because the paths are assumed to be partially coherent with one another. The second stage achieves additional gain by searching only over the physically possible arrangements of signals in the auto- and cross-correlation functions. These stages enable the matched-lag filter to behave like a matched filter within a matched filter. In a simple case, simulations of the matched-lag filter yield probabilities of detection that are, with one and two receivers, 4.5 to 290 times respectively that obtained from the alternative energy detector at a false-alarm probability of 0.001. The matched-lag filter has applications to communications and the detection of broadband signals such as from animals, vehicles, ships, nuclear blasts, and seismic events, and blind estimation of the impulse response of a multipath channel.
    • 在存在不确定方差的噪声的情况下,引入了一些带宽和未知波形和发射时间的源的检测问题。 信号沿着其延迟可能未知的路径行进到接收机。 使用称为“匹配滞后滤波器”的新接收机,根据接收信号的自相关和互相关函数来估计信号的存在或不存在。 相关函数的使用提供了信噪比增益的第一阶段,如匹配滤波器,因为假设路径彼此部分相干。 第二级通过仅搜索自动和互相关函数中的物理上可能的信号排列来实现附加增益。 这些阶段使得匹配滞后滤波器在匹配滤波器内表现得像匹配滤波器。 在简单的情况下,匹配滞后滤波器的仿真产生检测的概率,其中一个和两个接收机分别是以替代能量检测器以假警报概率为0.001获得的4.5到290次。 匹配滞后滤波器适用于通信和检测诸如动物,车辆,船舶,核爆炸和地震事件之类的宽带信号,以及对多径信道的脉冲响应的盲目估计。
