wsn-tracing
基于UP、UPF、CRPF的WSN目标跟踪算法,然后对
其基于CRPF的目标跟踪过程进行描述。(Based on the characteristics of low cost,low power,small size,high redundancy
and multi-function,it is more convenient,more reliable and more effective for WSN
to apply to target tracking than traditional system.)

Ground-based-SAR
The word Radar is the acronym of Radio detection and ranging. Radar is an active instrument, which measures the echo of scattering objects, surfaces and volumes illuminated by an electromagnetic wave internally generated belonging to the microwave portion of the electromagnetic spectrum. It was born just before the second world war for detecting and
ranging target for non-civilian scopes. In this case the requested spatial resolution was not so challenging for the technology available that time. The opening of new technological frontiers in the fifties, including the satellites and the space vehicles, demanded a better
spatial resolution for application in geosciences remote sensing (RS). Synthetic aperture radar (SAR) technique was invented to overcome resolution restrictions encountered in
radar observations from space and generally to improve the spatial resolution of radar images.(The word Radar is the acronym of Radio detection and ranging.

一种未知信源数的高分辨DOA 估计算法:众多性能优良的超分辨波达方向(DOA)估计算法通常需要预先判定信源数目,然而,现有的信源数估计
算法在有限采样快拍条件下,估计性能随着信噪比的降低而下降,错误概率也相应增加,最终导致DOA 估计失败。
该文提出一种超分辨的DOA 估计算法,此算法不需要预判信源个数和进行特征值分解,同时在时变环境中,针对
快拍数较少的情况下,依然保持较高的角度分辨能力,可以被认为是综合了Capon 法和MUSIC 法的优点。(Algorithm on High Resolution DOA Estimation
without Sources Number:Many of the super resolution DOA(Direction-Of-Arrival) estimation algorithms presume the number of
signal sources. Since the sample snapshot is limited, however, the available algorithms on source number estimation
may fail at lower SNR. In this paper, a novel algorithm for high resolution DOA estimation is proposed, which not
only skips sources number estimation and EVD, but also behaves satisfactorily with a few snapshot, it may be
viewed as a combination of merit of conventional Capon and MUSIC method.)

选取windows系统自带的ding.wav信号作为分析对象,在Matlab软件平台下,利用函数wavread对音频信号进行采样,记住采样频率和采样点数,听一下原始声音sound(y, fs, bits)。
(2)音频信号的频谱分析,先画出音频信号的时域波形;然后对音频号进行快速傅里叶变换fft(y,N),N取32768,画出信号的频谱特性,加深对频谱特性的理解。
(3)根据频谱,反演时域特性,画出时域波形。寻找幅值最大的两个频率,此频率除以fft点数在乘以采样频率就是信号的主频,即可合成信号的时域图形,听一下声音。
(4)对原音频信号进行1024点的分段付立业分析meshgrid
(5)根据主要频线合成音频,并画出时域图形,试听合成效果。
(6)采用线性插值(linspace)和傅立业反变换(fliplr, ifft)分别合成音频,并画出时域图形,试听效果。
