Analysis of the performance of a multiband passive bistatic radar processing scheme

Multiband FM‐based passive bistatic radar: target range resolution improvement

“…The results showed that the range resolution was improved, although the cross‐correlation function in the range was very peaky, as described in [11, 12]. After that, the authors [14, 15] extended the ideas presented in [12, 13], and give a mathematical framework to deal with different non‐regular spaced carrier frequencies of the FM and DVB‐T signals, respectively. The work of [16, 17] proposed two approaches based on multichannel and wideband autocorrelation to improve target range resolution exploiting multiple adjacent DVB‐T channels of the same IO, and analysed the application of these techniques with the same range resolution performance to real data.…”

“…To the best of our knowledge, this is the first paper to be directly related to the range resolution improvement problem based on the detection theory. There are some works in the two main classes of PBR systems: analogue transmitters like FM radio and so on, and digital transmitters like DVB‐T and so on, which focus on the usage of multiple channels of the same illuminator of opportunity (IO) in order to improve target range resolution [11–18]. For example, the paper of [11] showed that the range resolution can be improved by combining several FM radio channels at the cost of some ambiguities at the output of multichannel autocorrelation function.…”

Maximum‐likelihood angle estimator for multi‐channel FM‐radio‐based passive coherent location

“…Several studies on multi-channel FM-based PCL systems have been recently conducted in order to improve the performance of the parameter estimation and probability of detection of the target echo signal [13][14][15][16][17]. In addition, the range resolution of the FM signal can also be improved by exploiting the multi-channel FM structure [18,19].…”

Detection of fast maneuvering air targets using GSM based passive radar

“…An additional benefit is the bistatic geometry of passive radar, which allows the detection of low RCS (Radar Cross Section) targets, such as stealth targets [1][2][3][4]. Up to this current point in time, numerous PCL radar demonstrators have been developed [1], [5][6][7][8][9][10]. The most mature passive radar technology uses FM, DAB and DVB-T transmitters of opportunity as a source of illumination [1], [5][6][7][8][9][10].…”
