Experimental parameter estimation of vehicles GPS shadows by Forward scattering systems

Comparative Analysis of Two GPS Forward Scattering Systems For Cars Parameter Estimation

“…In the processing, the obtained navigation message is integrated every two hundred milliseconds in order to form the radio shadow of the moving object. The algorithm proposed in [10] is used for estimation of the received GPS shadow parameters (duration, depth, energy and power). The obtained GPS shadow parameters can then be used to classify moving objects (people, cars, buses, airplanes), for example, through the Data Mining approach [11].…”

“…The parameters of GPS shadows, used in this paper, are the same as in the article [10]. The registered GPS radio shadows (for example, in Fig.…”

“…A possible algorithm for target detection using GPS L5-based FSR system is described in [6], and the detection probability characteristics are analytically calculated in [7]. The next few articles [5][6][7][8][9][10][11][12] are devoted to experimental measurements made by using GPS L1-based FSR system and the Software-Defined GPS receiver, developed by the Aerospace Department in the University of Colorado [13], allowing to observe the geometric shadows (signal blocking) of ground objects of different sizes, mobile and stationary. The obtained recordings are not available for processing in the field conditions because the processing of radio shadows of objects requires the additional time in the laboratory, which further impedes research.…”

Target moving trajectory estimation by multiple receivers based on GPS forward scattering radar

“…According to the characteristics of GNSS signal amplitude when the target appears, GPS FSR can be used to identify the ground target [6]. A series of experiments using GPS L1 and L5 frequency bands for air target detection were also conducted in [7–9].…”
