Dim target detection using high order correlation method

Dim Target Detection System Based on DSP

The research on distributed system’s dim target detection and tracking is very important to improve the performance of infrared guard system. When the image background is very intricate, and there are few pels of targets, it is very hard to check the target. An local texture analysis method which is very fit for dim target detection in low signal to noise rate was adopted to realize the detecti...

High Speed Dim Air Target Detection Using Airborne Radar under Clutter and Jamming Effects

The challenging potential problems associated with using airborne radar in detection of High Speed Maneuvering Dim Target (HSMDT) are high noise, jamming and clutter effects. The problem is not only how to remove clutter and jamming but as well as the range migration and Doppler ambiguity estimation problems due to high relative speed between the targets and airborne radar. Some of recently pub...

Robust Target Detection Using Order Statistic Filters

In radar, sonar, and ultrasonic detection system, interference due to clutter can severely deteriorate the quality of the received signal to the point of concealing the target. This paper presents theoretical analysis of order statistic processors for improved target detection. The sort function is used to provide in s i i t into the optimal rank for detection of various targets and clutter env...

Multiple single pixel dim target detection in infrared image sequence

It is difficult to detect and classify multiple point targets in the presence of clutter and noise, in air borne IR image sequence. Most existing approaches assume target of several pixels size or of Gaussian shape with variance of 1.5 pixel. We propose a wavelet based detection technique for multiple single pixel dim targets in IR image sequence in the presence of clutter and noise. Temporal m...
