An integral equation method is used for the modeling of electromagnetic scattering from a rotating propeller, of which the length is about half a wavelength. This provides a convenient way of calculating its backscattering spectrum that is useful, fo

In passive radar systems the direct path interference strongly limits the detection performance, and demands the application of high resolution ADCs (Analog to Digital Converter). In this paper a direct path interference suppression technique is pres

Electromagnetic scattering from propellers of small-sized Unmanned Aerial Vehicles (UAVs) is studied in this work. Previous works have shown that rotating propeller blades produce significant fluctuations of the Radar Cross Section (RCS) in the case

The detection performance of a passive radar systems is generally determined by the received reference and surveillance signals purity. In recent times a number of interference cancellation techniques have been researched to deal with the disturbance

The detection performance of the passive radars systems is limited by the direct path interference. The application of digital beamforming antenna arrays in the surveillance channel has been proposed so far. The suppression can be accomplished with t

The radar cross section of small-sized unmanned aerial vehicles can be extremely low, making the perception of such objects impossible by standard radar techniques. However, the typical propeller size of these vehicles gives rise to a resonant behavi

Passive radars exploit the already existing signals in the environment to detect targets. The available sources of illuminations have a very wide range both in frequency of operation and bandwidth. The capability of fast and effective reconfiguration

This paper addresses the design and evaluation of monopulse antenna array used in UAV on-board collision avoidance radar. The antenna array use the advantages of the fractal geometry. The inverted Koch square patch fractal antenna has been modified i

A Passive radar system is able to operate fully independent of illuminators of opportunity. In most cases these illuminator sources are traditional telecommunication or broadcast signals. During the design of a passive radar we are trying to exploit
