A passive radar is a radar which uses external noncooperating transmitters (e.g. FM radio or GSM) to illuminate the target. Typical passive radar receiver benefits from its long integration time with a good velocity (Doppler frequency) estimation accuracy, while - especially for a GSM-based radar - the range measurement accuracy may be poor.

This paper presents the theory and experimental result of passive radar using WIFI transmitters as illumina-tors of opportunity. As a result of experiments conducted on 17th August 2013 at airfield Chrcynno a Cessna C208 airplane was detected using multistatic passive radar system based on low power signal from WIFI network nodes, which were acting as(More)
We present in the paper results of a generalised micro-Doppler analysis that is suited to high range resolution radar. The target echo energy is here represented in the three dimensional space of time, Doppler, and additionally range, what can provide more information on target micro-motion than the standard micro-Doppler analysis which is performed in the(More)
This paper presents the design and implementation of a C-band Analog-Front-End (AFE) for Frequency Modulated Continuous Wave (FMCW) Radar. This AFE is based on commercial off-the-shelf (COTS) radio frequency components. The system was designed to be used in various radar applications, including short range mode, Synthetic Aperture Radar (SAR) and Inverse(More)
A Wi-Fi based passive radar can be used for localization of objects in the vicinity of several access points, which are used as illumination sources. However, the transmission of Wi-Fi signal is not continuous - the activity of access points depends on the transmitted data and is totally unpredictable from the passive radar point of view. As a result, the(More)
