JNAM: a new detector proposed for marine radars |
|
| چکیده انگلیسی مقاله |
The proposed detector in this paper was obtained from a combination of adaptive and clutter-map detectors. Detection power of detectors has been studied in homogeneous and non-homogeneous environment (presence of interference targets) through MATLAB simulation software. The k-distribution proved to be the best option to display distribution of sea clutter, while k-distribution was assumed for sea clutter in simulation. On the other hand, CA-CFAR detector performed best in homogeneous conditions, and also the Ex-CFAR detector was suggested to improve the resistance of CA-CFAR detector against the interfering targets. The proposed detector performance was compared with these two detectors and with the ideal detector acquired from Marcum and Swerling equations, in homogeneous and non-homogeneous environment. Performance of the detectors in the presence of sharp clutter (which represents the fast clutter that make most difficult for CFAR detectors) and broad clutter (which represents the slow clutter) was investigated. Moreover, the performance of detectors in terms of data processing speed was discussed. Swerling ш model for oscillating signal target was received along with the detection of a signal pulse which was also considered in all simulation. |
