A method (1300, 1400, 1500) of operating a transponder detection device that includes at least one processor, at least one nontransitory processor-readable medium communicatively coupled to the at least one processor and which stores at least one of instructions or data executable by the at least one processor, the method comprising: - obtaining a number of subsamples, each of the subsamples associated with a respective delay period equal to a respective fraction of a nominal tag response signal period, the respective fractions different from one another, each of the number of subsamples obtained by: -- during each of a plurality of successive interrogation cycles associated with each of the number of subsamples, --- emitting a periodic electromagnetic interrogation signal during a transmit portion of the interrogation cycle; --- receiving electromagnetic signals during a receive response portion of the interrogation cycle that follows the transmit portion of the interrogation cycle; and --- waiting the delay period before a start of each of the successive interrogation cycles of the plurality of interrogation cycles, characterized in that - for each successive pair of subsamples, the delay period associated with a first successive one of the pairs of subsamples is less than the delay period associated with a next successive one of the pairs of subsamples, in particular less than the delay period associated with a next successive one of the pairs of subsamples by a duration approximately equal to the nominal tag response signal period divided by the number of subsamples. - obtaining a number of subsamples, each of the subsamples associated with a respective delay period equal to a respective fraction of a nominal tag response signal period, the respective fractions different from one another, each of the number of subsamples obtained by: -- during each of a plurality of successive interrogation cycles associated with each of the number of subsamples, --- emitting a periodic electromagnetic interrogation signal during a transmit portion of the interrogation cycle; --- receiving electromagnetic signals during a receive response portion of the interrogation cycle that follows the transmit portion of the interrogation cycle; and --- waiting the delay period before a start of each of the successive interrogation cycles of the plurality of interrogation cycles, characterized in that -- during each of a plurality of successive interrogation cycles associated with each of the number of subsamples, --- emitting a periodic electromagnetic interrogation signal during a transmit portion of the interrogation cycle; --- receiving electromagnetic signals during a receive response portion of the interrogation cycle that follows the transmit portion of the interrogation cycle; and --- waiting the delay period before a start of each of the successive interrogation cycles of the plurality of interrogation cycles, characterized in that --- emitting a periodic electromagnetic interrogation signal during a transmit portion of the interrogation cycle; --- receiving electromagnetic signals during a receive response portion of the interrogation cycle that follows the transmit portion of the interrogation cycle; and --- waiting the delay period before a start of each of the successive interrogation cycles of the plurality of interrogation cycles, characterized in that - for each successive pair of subsamples, the delay period associated with a first successive one of the pairs of subsamples is less than the delay period associated with a next successive one of the pairs of subsamples, in particular less than the delay period associated with a next successive one of the pairs of subsamples by a duration approximately equal to the nominal tag response signal period divided by the number of subsamples.
