Embodiment Construction
[0040] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0041] In view of the existing parameter estimation methods, multi-dimensional search is performed in the parameter domain, or combined with filter banks for analysis in the time-frequency domain, there is a large amount of calculations caused by multi-dimensional search in the parameter domain; it is difficult to analyze and extract characteristic parameters in the time-frequency domain. Issues affecting estimation performance. The chirp continuous signal feature extraction method proposed by the invention can be applied to symmetrical triangular chirp continuous wave signals, and can also be applied to chirp pulse signals...
