This paper describes a new method for Cross Ambiguity Function (CAF) plane processing for simultaneous detection and estimation of Time Difference of Arrival and Frequency Difference of Arrival of signals received at two spatially separated receivers. Computation of the CAF plane is done in subbands ...
Due to the mismatch between transmit waveforms and receive filters, Cross-Ambiguity Function (CAF) shaping plays an important role in the design of cognitive radar waveforms and allows more freedom for waveform optimization problem than conventional ambi
Cross ambiguity function (CAF) is the key function for successful location tracking for passive radar systems. This paper describes several methods of the CAF based on block processing. The computation time of the CAF is a challenging problem for parallel programming techniques. In this paper the ...

11.The method, based on cross-ambiguity function, is more suitable for time delay estimation in low SNR.这种基于互模糊函数的算法与传统的直接互相关法相比,更适用于低信噪比情况下的时差估计。 12.Fast template matching algorithm based on boundary cross correlation and image integration基于互相关边界特性...
cross- correlation function, Linear canonical Wigner distribution, Weak signal detection 1 Introduction In recent decades, the linear canonical transform (LCT) has been attracted much attention due to its significance in optics propagation [1], time-frequency analysis [2], and signal processing [3...
Essentially, a TF kernel acts as a two-dimensional (2-D) low-pass filter or mask multiplied in the ambiguity function (AF) domain, expressed with respect to time lag and frequency shift. TF kernels are designed based on the fact that, typically, autoterms have high values around the ...

will focus on improving further the coverage of our conceptual interlingua resources and the efficiency of our document processing modules. We are also investigating the construction of an interlingual resource of proper nouns, using technology from other TextWise products, since proper nouns constitute ...

These findings also reveal an important characteristic ofhuman cognitionthat we would not have been able to uncover unless we had studied bilinguals. Quite remarkably, syntactic processing in the native or first ...
