摘要：

We describe an efficient technique analyzing signals that comprise a number of polynomial-phase components, The technique is based on a recently proposed "multiple frequency tracker," which is an algorithm for recursive estimation of parameters of multiple sine waves in noise, It has a relatively low SNR threshold and moderate computational complexity.
