The watermark consists of a pseudorandom sequence and its strength is modulated according to the local image characteristics 水印为二值伪随机序列,其强度可通过局部图像特征来调节。
The pseudorandom sequences have wide applications in the practice, so the design of sequence generators is always the central task 伪随机序列在实际应用中有广泛的用途,因此序列生成器的研究一直是非常重要的一个课题。
If the icon is not matched with the characters of pseudorandom sequence, an alarm issued . if the tunnel is broken, the icons are not displayed on monitor until sending out a control signal from central monitor room 如果线路被破坏,监控端给出的确认标识将不再显示(除非远程监控室发送控制信号),从而检测出被监控方破坏监控头系统的行为,有效防止因信号传输线路被随意改动而导致伪图像的引入。
1 in the research of design of radar waveform, one kind of hybrid radar waveform obtained by combining the chirp waveform with the non-periodic pseudorandom sequences is discussed . through the theoretical analysis and computer simulation, several main characteristics of this kinds of hybrid waveforms are discussed, such as the ambiguity function, ambiguity graph, the spectrum, the weighting methods, the response of the processing filter and the low probability of interception . those are showing the effectiveness of the new hybrid waveforms on the performance of high resolution and low probability of interception 作者在以下几个方面的研究工作中取得了进展及创新:1、在雷达波形设计中,介绍了一类新的线性调频信号与非周期随机编码信号相结合的组合波形的组合形式,通过理论分析和大量的计算机模拟研究了这类组合波形的模糊函数(图)、频谱特性、多普勒频移特性、加权输出特性、低截获等方面的特点,证明了新型的组合波形在高分辨、低截获等方面的有效性。
