| titleOfInvention | Method for detecting coherent accumulation of maneuvering turning target |
| abstract | The invention relates to a coherent accumulation detection method for a maneuvering turning target, which comprises the following steps: receiving radar echo signals and carrying out demodulation and pulse compression processing; setting a search parameter discretization numerical value; traversing the corresponding search ranges of all the search parameters, determining a search track according to an accurate distance evolution equation of a maneuvering turning target for each group of search parameters, extracting target data, compensating phase fluctuation among different pulses by using the accurate distance evolution equation, and adding compensated data vectors until the accumulation output of all the search parameters is completed, thereby obtaining a coherent accumulation output matrix; performing constant false alarm rate detection by using the coherent accumulation output matrix, and judging whether a target is detected; and if the target is detected, estimating a target motion parameter according to the peak position coordinate of the target, and outputting a target motion trace. The method can eliminate the distance migration and Doppler migration effects caused by the turning motion of the target and realize the coherent accumulation and detection of the maneuvering turning target. |
