图片分类可用作图像搜索引擎的预滤波，以降低图像检索时的图像匹配数量，提高检索速度。
The image classification can be used as a pre-filter of the image search engine to reduce the amount of image matching, and speed up the image index processing.
本文详细介绍了以下几个方面：线性调频信号的波形、匹配滤波器、模糊函数、速度分辨力、距离分辨力及抗干扰能力；
This paper gives a detailed account of the waveform, matched-filter, fuzzy function, resolution in speed, resolution in range and the capacity of anti-interference of the Chirp signal.
讨论了匹配测量数据的平滑、滤波和外推问题。所谓匹配测量数据是指位置参数和速度参数呈求导的匹配关系。
In the problem of smoothing, filtering and predicting matching data in aerospace measurement, matching data refers that velocity parameter is differential of position parameter.
根据匹配滤波器输出峰值位置可以获得目标距离的估计，但运动目标径向速度造成的回波和样本失配将导致匹配滤波器检测性能下降。
But the mismatch between echo and replica caused by moving target's radial velocity will degrade the detecting performance of the matched filter.
