Radon Spectrum and Its Application for Small Moving Target Detection
نویسنده
چکیده
Analogous to the radar Doppler spectrum for coherent processing, the concept of a Radon spectrum that is a kind of normalised Radon transform is proposed and used for radar non-coherent detection. One advantage of using the Radon transform for non-coherent processing is that integration in all directions is considered, and hence range migration of moving targets is not a concern. The detection processing is based upon a 2D Radon spectrum that is transformed from the original range-time 2D radar image. The threshold and the probability of detection for a given false-alarm rate are determined in the same way as the traditional non-coherent integration. Both simulated and real radar datasets are tested and the effectiveness of the proposed technique is demonstrated. RELEASE LIMITATION Approved for public release

Application of Radon Transform in Detecting Turning Angle of Bodies and in Reading Multi - Lingual Documents
Recently, image processing technique and robotic vision are widely applied in fault detection of industrial products as well as document reading. In order to compare the captured images from the target, it is necessary to prepare a perfect image, then matching should be applied. A preprocessing must therefore, be done to correct the samples’ and or camera’s movement which can occur during the...

متن کاملTarget Detection in Bistatic Passive Radars by Using Adaptive Processing Based on Correntropy Cost Function
In this paper a novel method is introduced for target detection in bistatic passive radars which uses the concept of correntropy to distinguish correct targets from false detections. In proposed method the history of each cell of ambiguity function is modeled as a stochastic process. Then the stochastic processes consist the noise are differentiated from those consisting targets by constructing...
متن کاملThe X-ray Transform and its Application in Nano Crystallography
In this article a review on the definition of the X- ray transform and some ofits applications in Nano crystallography is presented. We shall show that the X- raytransform is a special case of the Radon transform on homogeneous spaces when thetopological group E(n)- the Euclidean group - acts on ℝ2 transitively. First someproperties of the Radon transform are investigated then the relationship ...
