abstract according to the adventages of passive radars they have been reconsidered recently due to development of signal processing technology. in the field of sea targets detection using passive radar few research have been reported. this paper presents a new method to detect sea targets using adaptive filter weights variation model and using the fact that the radar cross section of sea target...

Passive Bistatic Radar (PBR), or Passive Coherent Location, is gaining interest in the radar community as it provides some advantages with respect to active radar. Although, passive radar does not aim to replace active radar, it provides a good complement to it. The computational effort that is required to implement the required signal processing is one of the drawbacks that affect passive rada...

Abstract: This paper proposes a novel scheme for multi-static passive radar processing, based on soft-input soft-output processing and Bayesian sparse estimation. In this scheme, each receiver estimates the probability of target presence based on its received signal and the prior information received from a central processor. The resulting posterior target probabilities are transmitted to the c...

In the part of radiolocation focused on one target tracking we can find for example active radar and passive surveillance systems but we cannot find any representative of passive radiolocation area. Therefore this paper is focused on the conceptual design and practical solution of passive radar for one target tracking. The scanning of the area of interest is ensured by an antenna system with a ...

CFAR (Constant False Alarm Rate) detectors were designed and evaluated in non-homogeneous DVB-T (Digital Video Broadcasting-Terrestrial) passive radar scenarios. The CA-CFAR (Cell-Averaged CFAR) is the most widespread incoherent CFAR technique. CA-CFAR detector is optimal under the assumption of homogeneous interference, but CA-CFAR performance is degraded when this assumption is not fulfilled....

In this paper we investigate the dynamic range requirements of a passive radar system and show the impact of analogto-digital converter (ADC) quantization on system performance. This analysis is carried out with a view towards understanding how many ADC bits are required in each channel of the passive radar system. To give practical insight, we consider the parameters of a passive radar system ...

This tutorial describes the basis of passive bistatic radar (PBR) systems, and in particular the nature of the waveforms of illuminators of opportunity that they exploit. It shows that there is a wide variety of such waveforms, from broadcast, communications and radionavigation transmissions, and that in general they are not optimum for radar purposes. In addition, they usually vary significant...

The passive bistatic radar (PBR) system can utilize the illuminator of opportunity to enhance radar capability. By utilizing the forward scattering technique and procedure into the specific mode of PBR can provide an improvement in target detection and classification. The system is known as passive Forward Scattering Radar (FSR). The passive FSR system can exploit the peculiar advantage of the ...
