In this paper we build upon recent work in the radio astronomy community to experimentally demonstrate the viability of passive radar for Space Situational Awareness. Furthermore, we show that the six state parameters of objects in orbit may be measured and used to perform orbit characterisation/estimation.
In this paper, we compare and contrast code, time and spatial domain signal processing techniques for mitigating the effects of the ambiguities present in single frequency network digital broadcast signals in passive radar. By performing these additional processing steps, the number of ambiguities present in the range Doppler scene will be reduced by approximately one third or a half (situation dependant)...
This paper provides a detailed overview of the Digital Video Broadcasting Terrestrial (DVB-T) signal structure and the implications for passive radar systems that use these signals as illuminators of opportunity. In particular, we analyze the ambiguity function and explain its delay and Doppler properties in terms of the underlying structure of the DVB-T signal. Of particular concern for radar range-Doppler...
Passive Bistatic Radar exploits the illumination of a scene by a local communications transmitter in order to perform radar processing without dedicated transmitter hardware. The direct transmission and strong stationary clutter are often present in the surveillance signal, reducing dynamic range and masking returns from targets. In this study various adaptive filters are used to estimate the direct...
In this paper we investigate the dynamic range requirements of a passive radar system and show the impact of analog-to-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 which...
