摘要
疯爬算法可以用于平面极大值点的搜索以及平面脊线的提取,它具有抗噪性能优良以及可以提取多脊线等优点。在深入研究经典疯爬算法的基础上,引入了超级弹簧、计量矩阵、淬火冷却等一系列新的概念,完善了疯爬算法的理论体系,提出了一套改进疯爬算法。并将其应用于噪声环境下,交错跳频信号小波尺度图脊线的提取。在获取了信号跳频图案的同时,验证了改进算法的有效性。
Crazy climber algorithm could be used to search the local maximum points on the plane and extract the ridge line from the plane.It has strong antinoise ability and could extract more ridge lines.This paper further studied classical crazy climber algorithm,imported a set of new concepts,such as super spring,measurement matrix,quenching cooling and so on.It perfected the theory system of crazy climber algorithm,and presented an improved crazy climber algorithm,which could be used to extract the ridge lines from the wavelet scalogram of the interlaced frequency-hopping signals in the noise environment.The validity of the improved algorithm is verified when the frequency-hopping pattern is obtained.
