The probability of detection associated with theoutput ranges depends upon the receiver sensitivities.LEARNING OBJECTIVES Interpret PV. If you are attempting to verify ESM interceptoutputs to assess vulnerability of variousranges achieved by your own receiver, remember thatPV outputs maximum intercept ranges. If a platform’semitters. Identify limitations and assumptions.Interpret an example output of the PV program.emitters aren’t turned on at that range, there will benothing to intercept.FUNCTIONAL DESCRIPTIONPV provides estimates of the vulnerability of thevarious emitters on a platform to a specified ESMESM computes the maximum ESMR of an emitter.system under varying environmental conditions. ESMESMR is computed only if the emitter’s frequency fallsestimate is expressed as the maximum intercept rangewithin one of the frequency bands of the receiver. Tablefor each emitter.
