MONITORINGTARGET SPEEDS
Once theradarhasbeenproperlysetup andtested (see precedingsections), itisreadyfor
use. Acquiringanddisplayingvalidtarget(andpatrol)speedsrequiresobtainingaproper
trackinghistory, asdescribedbelow:
1.Visuallyobservetargetvehicleandestimateitsspeed.
Recheck antennaaim andMOV-STAselection.
Observe othervehicleswhichmaybeintheradarbeamandwhicharepotential
targets(ormayblocktheradar's"view"oftheselectedtarget), especiallythosewhich
arelarger, closer, ormuchfaster thantheselectedtarget.
Bealert toterrainorroadsidefeatures, whichcancauseinterference, incorrect
readings, ordisplayblanking. (Suchfeaturesincludepowerlines, radio/TV
transmitters, bridges, guardrails, andotherlargereflectors, etc.)
2.ListentotheDoppleraudio. Thepitchofthetoneshouldcorrespondtothevisual
estimatemadeabove. Thetoneshouldbeclearandstrong;scratchy, “buzzy”, or
garbledtonescouldindicateinterference ofsomesort.
3.ChecktheradarTARGET display. Thereadingshouldcloselymatchthevisual
estimateandthepitchoftheaudiotone.
4.IfyouareoperatinginMovingMode, checkyourspeedometeragainstthePATROL
display. Thereadingsshouldcorrespond. Discrepanciesindicatetheradarisreading
thePATROLspeedincorrectly, andthusdisplayinganincorrectTARGET speed.
CommoncausesofincorrectPATROLreadingsarelargereflectors(suchastrucks)
immediatelyaheadofthepatrolvehicleorattheroadside. Ifthisisthecase, passing
orputtingmoredistance betweenthepatrolvehicleandthereflectorshouldclearup
thediscrepancy. Properantennaaimingwill helpeliminatecosineerrorinthe
