A Discrete Clutter Reduction Method for Drone Detection with High Resolution Radars
نویسندگان
چکیده
The paper deals with a problem of noise reduction for drone detection high range resolution radars. considered discrete clutter includes land vehicles, birds, etc. This involves in the radar echo signals and could not be rejected by using classical methods, example moving target indicator (MTI) (MTD). As result, this forms false alarms on screen. To reduce we propose new method which is based target’s Doppler dispersion characteristic. study integrated tested variety drones different scenarios. test results show that proposed achieves better performance than one recently published.

A Statistical Clutter Suppression Method Based on Given Target-Existence Probabilities for High Resolution UWB Radars
High-resolution radars (HRR) using ultra wideband (UWB) signals is a promising system for various detection and ranging applications. The radar resolution increases as a decrease of the pulse width, then radar echoes including background unwanted ones become spiky. Various modifications of constant false alarm rate (CFAR) and matched filters have been proposed to reduce false alarm induced by u...

متن کاملArtificial Neural Network-Based Clutter Reduction Systems for Ship Size Estimation in Maritime Radars
The existence of clutter in maritime radars deteriorates the estimation of some physical parameters of the objects detected over the sea surface. For that reason, maritime radars should incorporate efficient clutter reduction techniques. Due to the intrinsic nonlinear dynamic of sea clutter, nonlinear signal processing is needed, what can be achieved by artificial neural networks (ANNs). In thi...
متن کاملA capon beamforming method for clutter suppression in colocated compressive sensing based MIMO radars
Compressive sensing (CS) based multi-input multi-output (MIMO) radar systems that explore the sparsity of targets in the target space enable either the same localization performance as traditional methods but with significantly fewer measurements, or significantly improved performance with the same number of measurements. However, the enabling assumption, i.e., the target sparsity, diminishes i...
متن کاملimproving fluctuating target detection using high range resolution stepped frequency radars
one of the problems in detecting radar targets is the variation of target cross section due to aspect angle; which is named as target fluctuation. this perfectly depends on target geometry and transmitted wavelength and can cause significant loss of detection. one of the solutions to this is improving the radar range resolution. stepped frequency is one of the signals that can improve the range...
