Target detection within sea clutter based on combined fractal characteristics

open access: closed2017 20th International Conference on Information Fusion (Fusion), 2017
Using fractal dimension or one of other fractal characteristics to detect targets in sea clutter, it is often difficult to distinguish at low signal-to-clutter ratios. To solve this problem, a new method for target detection in sea clutter based on combined fractal characteristics is proposed.

Range-ambiguous clutter characteristics in airborne FDA radar

Signal Processing, 2020
Abstract Frequency diverse array (FDA) has received much attention in recent years. Different from classic phased-array (PA) that uses the same carrier frequency for all array elements, FDA adopts a small frequency increment across its array elements to produce angle, range and even time dependent transmit beampattern, which provides many promising ...
