| Abstract: | The performance of random parameter pulse train (RPPT) detection for high range resolution radar is a large improvement on conventional detection's, but its calculation complexity and slow operation speed restrict the usage. Based on the characteristics of the detection likelihood ratio sequence and the recursive relations, a fast algorithm is proposed. Analysis and simulation show that the operation speed of the algorithm, compared with the direct calculation, is advanced by about 10 times, so it has larger practicality and can be used in real- time detection. |
