Target Detection Using a GPS Forward-Scattering Radar

Feasibility of Cosmic Object Detection Using a Solar FSR System

“…1). In this case, this blocked signal at the receiver input URx can be represented as a sum of the direct unobstructed signal Ui and the blocking shadow signal Ushadow [6][7][8][9]…”

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

“…Then the estimates of the parameters (duration, depth, energy and power) of the resulting GPS shadows are automatically calculated based on the algorithm proposed in the article [11]. The thus obtained parameters of the GPS shadows of the two cars are represented in the form an Excel-table for the subsequent generalized statistical processing [11,12]. The preliminary rough assessment of the GPS shadow parameters of the car recorded by the two different GPS signal recording systems (GPS receiver 1 -is the GPS signal recording system developed by the Colorado University and GPS receiver -2 is the GPS signal recording system Stereo dual GNSS front-end) can be done by comparing their statistical parameters (Mean and STD).…”

“…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.…”

Using Heterogeneous Satellites for Passive Detection of Moving Aerial Target

“…Passive target detection using satellite illumination is an important application in satellite systems, which utilizes signals to detect moving targets through signal processing technologies [4,5]. Most existing works on passive target detection makes a strong assumption of a single satellite, in which only signals for a single satellite need to be processed [6][7][8][9][10]. However, in practice, a receiver in passive target detection is likely to receive illumination signals from different satellites.…”
