Ground Penetrating RADAR in Anadvertisement stating that GSSI's GPR is used in Law & OrderSpecial Victims Unit (S05E09: Control) so we start this list with a realistic depictionof GPR. Criminal Minds S01E14 (2006) (starting at 1365 seconds) with a beeping screen when theskeleton is seen. This reference was identified after reading From Criminal Minds to CSI: the rise of Ground Penetrating Radar in clandestine investigations (Aug. 2019).a radar profile starts Millennium (S02E15: Owls) and is actually not toobad. The radargram is again shown briefly on a screen later in the same episode. Columbo (Columbo likes the night life, end) looks like they are considering a SAR solution since even though theGPR is only moved in one direction, a 2-D image is generated. NCIS (episode 9, season 1, 31 min. from the beginning). CSI NY (episode 20, season 6, 1 min. 40 sec. from the beginningand episode 20, season 2). The newer seasons of the series (Season 14, Episode 18)is hardly better, with a radargram scrolling from top to bottom.CSI Miami (season 4, episode 18 -- Double Jeopardy --and season 6, episode 18) is correct in the script but notin the image (shows a gun buried in concrete, but the actor speaks of a hyperbolic reflection,so ... half correct). Despite an initial attempt to get the science right in Bones(season 1, episode 7, 34 min 11 sec), the producers seem to have thought that the audience wasnot up to the task of thinking and reverted to the same idiocy as the other series(Bones (season 5, episode 1, 5 min. 38 sec) in which GPR evenallows for identifying the material a reflector is made of. X-Files (season 1, epidosde 20) has an episode with a briefscene using GPR plotting on paper and a display on an echography-like screen not showing much otherthan noise (as observed in real life ? but why the cone-shaped field of view ?Scully:"An experienced operator attempts to differentiate if the signal is a body oris stone or a hole in the ground.").As opposed to the statement on the GSSI webpage, I have not found reference to GPR in Jurassik Park, although there is a scene usingseismic in which they detect centimeter-scale bones using meter-long waves (but then ... I haveno expertise with seismic ...). I am greatful though to the GSSI Marketing Communications Manager for kindly providing the necessaryinformation for locating the episode of Crossing Jordan,as stated on the GSSI web page andMTI web sites, for abrief reference to GPR and what looks like an actual, although static, radargram on the display. Hawaii Five-0 Season 2, Episode 7 (20 min. from beginning)needs 3 desktop LCD screens to display radargrams and beeps when bodies are "detected". Sanctuary (season 03, episode 16) does not bothershowing the instrument but just mentions its existence. Season 1, Episode 8 (620 seconds from beginning)of La Casa de Papel (Money Heist) -- in French here -- mentions GPR for detecting tunnelsburied 15-meters deep but not actual hardware shown. One "movie" refers to GPR, Return to Houseon Haunted Hill, but beyond exhibiting an inductively coupled metal detector, the movie isso bad that I did not bother checking if the GPR is actually used to find cavities.In the same vein, Flashpoint ("One Wrong Move") episode 14 ofseason 2, with a metal detector and some stuff glued to the coil. Lost Gold of WW2 (s01e06) (startingn at 405 s) is a real GPR radargram (finally !).Le Bureau des L gendes (season04,episode 5) exhibits the use of Through-the-Wall RADAR, closely related to GPR. Whilethe depiction of the SAR measurement when scanning the radar on the wall seems accurate,the image is not, nor is the vertical resolution nor is the time refresh rate (the actorwould have to scan the whole wall again for an updated image). In the "litterature", Dan Brown's Deception Point mentions GPR p.329 of the ebook version(Simon and Schuster, 2001): "Tolland helped her unpack the Ground Penetrating Radar and positionit on the ice. The instrument looked like three miniature snowplow blades that had been affixedin parallel to an aluminum frame. The entire device was no more than a yard long and was connectedby cables to a current attenuator and a marine battery on the sled.". So far so good, but then"Mike, I need to align the GPR transmitter with the meteorite site [...] All the work is in setup.The actual shot takes only a second." Wish it were ...Documentary excerpt, on the French/German ARTE channel,demonstrating the use of GPR in Petra (Jordan) for mapping underground structures.Expertise (?!) in the development of passive wireless acoustic transducers acting as sensors,with the SENSeOR company and the Time andFrequency department of the FEMTO-ST institute (Besan on,France), focuses on bulk- and surface-acoustic transducers and the associated RADAR-likeelectronics systems for the development of passive sensors interrogated through a wireless radiofrequency link.Previous activities (performed in IMEC, Leuven, Belgium, continued at FEMTO-ST) were concerned with the combination of Love mode surface acoustic wave sensors (SAW) [slides in French: presented 11/2006 at ENSL, France](videoof the presentation in French) and surface plasmonresonance (SPR) as well as quartz crystal microbalance (QCM) and atomicforce microscopy (AFM) combination. Older work performed during my PhD includes noise analysis in a chaoticelectronic circuit (Chua's circuit) and manipulation of nano/micrometricobjects with AFM with force feedback (inclusion of an AFM in an SEM). Iobtained my habilitation (HDR) in 2010 (manuscriptand slides). I am currently an associate professoremployed by the Universit de Franche-Comt in Besan on, France, located atthe Time and Frequency department of FEMTO-ST for my research activities. Following the3-month visit to Pr. M Sato's laboratory in CNEAS (Sendai, Japan) end of 2017,my activities have shifted towards (passive) RADAR and phased antenna array processing,still applied to passive acoustic sensor cooperative targets.

Warning: somemistakes in this paper, as was pointed out to us by a reviewer when submittingthis paper for publication in IEEE Trans. Ultrasonics, Ferroelectrics andFreq. Control: we model the propagation of the wave with a loss model followinga 1/d2 law. This is wrong in the case of a radar, where the target acts as apoint like source and hence only 1/d2 fraction of the energy reaching thetarget is used as the new source, yielding a 1/d4 behaviour (the classicalradar equation).

Gizeli mentioned to me an error whose exact expression I cannotremember. I believe this document states that the acoustic losses in anorganic layer is independent on the thickness, while the loss should berelated to the layer thickness as later stated by L.
