IDEPAR: a multichannel digital video broadcasting‐terrestrial passive radar technological demonstrator in terrestrial radar scenarios

Passive Radar Array Processing with Non-Uniform Linear Arrays for Ground Target’s Detection and Localization

“…The design of an array antenna to be part of the IDEPAR demonstrator [8], which has been used to test the algorithms, is one of the objectives of this paper. Figure 4 presents a functional block diagram of this multichannel DVB-T-based PRS.…”

“…Coordinates of the main elements of the geometry are presented in Table 8. In order to obtain the system coverage, the Bistatic Radar Cross-Section (BRCS) of the targets of interest was estimated in [8]. A Mazda 6 SPORT vehicle was considered as a representative target for traffic monitoring.…”

“…The coverage for only one Televés 4G NOVA antenna in the surveillance channel is depicted in Figure 18a, for P D = 0.8 and P FA = 10 −6 , using system parameters summarized in [8]. In [8], only basic propagation losses were considered; in this new study, WinProp (AWE Communications) software was used, including geographical data and taking into consideration that the desired targets were located on the ground. Results presented in Figure 18b confirm the range coverage improvement obtained using an array antenna in the surveillance channel.…”

“…IDEPAR was designed and developed for terrestrial and maritime scenarios, and its capabilities were evaluated in [8][9][10][11][12][13][14]. Taking into consideration the IDEPAR design requirement of using Commercial Off-The-Shelf (COTS) components to the greatest possible extent, the array is based on commercial UHF antennas.…”

“…This scenario was analyzed in [8], and the study is completed with a more accurate estimation of system coverage. In [8], only free space losses were considered. Taking into consideration that the desired targets are on the ground (cars), these estimations were really rough.…”
