Wireless transmission is becoming an increasingly widely available source of transmissions for passive radar detection. In this paper, we present a detailed analysis of the ambiguity function (AF) of a range of typical IEEE 802.11 signals obtained during a series of experimental trials. Theoretical analysis has been used to identify the average properties of basic signal types in terms of resolution...
In this paper the practical feasibility of a WiFi transmissions based passive bistatic radar (PBR) is analyzed. The required data processing steps are described there including the adopted techniques for: (i) the control of the signal Ambiguity Function usually yielding a high sidelobe level and (ii) the removal of the undesired signal contributions which strongly limit the useful dynamic range. The...
In this paper the use of Digital Video Broadcasting Terrestrial (DVB-T) signals is addressed for Passive Bistatic Radar (PBR). The impact of the synchronization accuracy is analyzed on the PBR Ambiguity Function (AF) shape in term of Peak to Side Lobe Ratio (PSLR), there including timing synchronization, frequency offset synchronization and frequency sampling offset synchronization. Different approaches...
In this paper the use of Digital Video Broadcasting-Terrestrial (DVB-T) signals as waveform of opportunity for Passive Bistatic Radar (PBR) is addressed. A new approach for DVB-T Cross-Ambiguity Function (CAF) evaluation is proposed, which exploits a linear filter based on the knowledge of the expected value of the ambiguity function. The proposed approach is able to remove the unwanted deterministic...
