Abstract

The invention discloses a target detection method and device. The target detection method comprises the following steps that an original video of a radar device is obtained; the original video is preprocessed on the basis of an automatic threshold algorithm to obtain a first video; plotting and tracking are conducted on the first video to obtain a small target, wherein the radar cross section of the small target is not smaller than 0.1 m<2>, and the height of the small target is not smaller than 1 m. Through the target detection method and device, the problems that small target detection equipment is poor in capacity and low in detection accuracy in the correlative technology are solved, small targets on the sea surface can be found accurately in time, the accident occurrence rate is reduced, and sensitivity and accuracy of a detection system are improved.

Description

technical field [0001] The invention relates to the field of ship and shore-based communication, in particular to a target detection method and device. Background technique [0002] Radar is an indispensable detector for ships and shore bases, but its target detection performance is often affected by sea clutter. Sea clutter, that is, the radar reflection callback from the ocean surface, is the main clutter source for radar detection in ships and shore-based related fields. Usually, unlike ground clutter, which is a distributed scattering phenomenon, it shows stronger dynamic characteristics. Therefore, the existence of sea clutter seriously affects the detection performance of radar on sea targets. [0003] At present, there are two main methods to deal with sea clutter: one is the sea clutter distribution model established based on traditional mechanics, such as Rayleigh distribution, Log-Normal distribution, Weibull ( Weibul) distribution and K distribution; another met...
