Analysis of radar detection performance for low altitude small target

2016 International Conference on Communication and Signal Processing (ICCSP), 2016
Radar usually employs several signal processing methods successively for detection. Each processing step influences the radar detection performance. Thus, analysis of the radar detection performance considering the complete signal processing flow provides significant reference for radar detector design.

Tracking Swerling fluctuating targets at low altitude over the sea

IEEE Transactions on Aerospace and Electronic Systems, 1991
Accurate tracking of targets flying at low altitudes above a smooth surface is difficult because of the surface reflection. The authors propose a solution based on deterministic physical modeling of the specular multipath and the maximum likelihood (ML) method.

Low-altitude target detection by coastline operated marine radar

IEEE Transactions on Aerospace and Electronic Systems, 1992
Relevant to a Richian family of fluctuating targets with a composite background of sea-plus-land clutter, the performance prediction of a radar operating in near-coastal regions is elucidated by assuming noncoherent integration of the pulses. Considering the dominance of land clutter, a modified K-distributed statistic is indicated for the overall ...

Taking account of the sea state in the tracking of targets at low altitude

Proceedings of Canadian Conference on Electrical and Computer Engineering CCECE-94, 1994
The authors use the refined maximum likelihood technique with a new approach in conjunction with FDPEM software to simulate the radar echoes of the target, while using ray-tracing as propagation model. FDPEM uses a finite difference method to solve the parabolic equation in order to simulate the wave propagation in space and considers the effect ...

Research on the OFDM Passive Radar System for Low-Altitude Target Detection

2018
Detection of low-altitude targets such as Unmanned Aerial Vehicles (UAVs) has practical implications on aviation regulation. In order to achieve a low cost-benefit ratio, a passive radar system based on the OFDM communication signal is applied to study the echo processing methods.

On exploring SVDSPM algorithm for more accurate DOA estimation of low altitude target

2010 International Conference on Wireless Communications & Signal Processing (WCSP), 2010
There exits SVDSPM (Singular Value Decomposition based on Signal Phase Matching Principle) algorithm for direction of arrival (DOA) estimation. Our aim is to present a different SVDSPM algorithm for more accurate estimation of low altitude target. So a void reference sensor is used to explore the possibility of better performance.
