- Abstract
- Drones are currently being used for various applications. However, the detection of drones
for defense or security purposes has become problematic because of the use of plastic materials and
the small size of these drones. Any drone can be placed under surveillance to accurately determine its
position by collecting high-resolution data using various detectors such as the radar system proposed
in this paper. The W-band radar has a high carrier frequency, which makes it easy to design a
wide bandwidth system, and the wideband FMCW signal is suitable for creating high resolution
images from a distance. Unfortunately, the huge amounts of data gathered in this way also contain
clutter (such as background data and noise) that is usually generated from unstable radar systems
and complex environmental factors, and which frequently gives rise to distorted data. Accurate
extraction of the position of the target from this big data requires the clutter to be suppressed and
canceled, but conventional clutter cancellation methods are not suitable. Four clutter cancellation
algorithms are assessed and compared: standard deviation, adaptive least mean squares (LMS),
recursive least squares (RLS), and the proposed LMS. The proposed LMS has combined LMS with
the standard deviation method. First, the big data pertaining to the target position is collected
using the W-band radar system. Subsequently, the target position is calculated by applying these
algorithms. The performance of the proposed algorithms is measured and compared to that of the
other three algorithms by conducting outdoor experiments.
