Other AbstractThe invention relates to a Hough transform-based track-before-detect method of multidimensional parameters. The method includes the steps of performing initializing to determine a target track initiation, as an initial detection result; allowing cycling for a third detection; according to a last detection result and characteristic parameters extracted via the current detection, performing differencing and comparison of judgment thresholds, and performing judging; according to judging results, tracking a target; performing filtering if certain characteristic parameter of the target is divergent, directly executing Hough transform if the characteristic parameter is not divergent, and performing energy accumulation; according to a target accumulated energy and an accumulative threshold, performing comparing, and performing adaptive updating and judging the threshold; using the target of the accumulative threshold as a final detection result, and starting a next cycle. The method has the advantages that the pre-detected track is avoided being divorced from actuality, false tracks are eliminated, and the ability of radar to detect, track and distinguish multiple moving targets is improved.
