PROJECT TITLE :

Range-spread target detection using time delay-frequency matched filter

ABSTRACT:

A novel time delay-frequency matched filter (t-f-MF) of a mixer output is presented during this study and it is used to style a brand new vary-spread target detector within the background of white Gaussian noise. 1st, the mixer output of a target is proved to be composed of several sinusoidal signals, and then the matched signal of the mixer output is made. Next, the authors use the matched signal to get the t-f-MF of a mixer output. The energy of the t-f-MF for the target signal concentrates around zero frequency, whereas that for the white Gaussian noise spreads over the entire frequency domain. According to the present, the authors design a range-unfold target detector that is capable of detecting a target with high velocity. The proposed detector is evaluated by measured radar data. Experimental results show that the proposed detector outperforms the traditional detectors. The results additionally show that the detector is sturdy against the target gesture.
