Abstract

Sposób okreslania charakterystyk lokalizacji nadajnika, emitujacego odpowiednie ciagi impulsów odbieranych przez co najmniej dwa odbiorniki, sposób obejmujacy procedury odbioru odpowiednich ciagów impulsów, przez kazdy z co najmniej dwóch odbiorników oraz rejestracji Czasu Przybycia (TOA) kazdego impulsu w odbieranych powtarzalnych ciagach impulsów, okreslania okresu powtarzania ciagu impulsów (PTRI) nadajnika, dla kazdego odbiornika, okreslania fazy TOA, kazdego odebranego ciagu impulsów zgodnie z PTRI oraz odpowiedniego TOA kazdego odpowiedniego ciagu impulsów, dla kazdego odbiornika, okreslajac odpowiednie krzywe charakterystycznych faz TOA odpowiednich odebranych ciagów impulsów, wedlug odpowiedniej fazy TOA odbieranych powtarzalnych ciagów impulsów oraz dla kazdej pary odbiorników, okreslania charakterystyk lokalizacji nadajnika zgodnie z krzywymi charakterystycznej fazy TOA wedlug ciagów impulsów odbieranych przez kazdy z odbiorników.A method for determining the location characteristics of a transmitter emitting the respective pulse trains received by at least two receivers, the method comprising procedures for receiving the respective pulse trains at each of the at least two receivers and recording the Time of Arrival (TOA) of each pulse in the received repetitive pulse trains, determining the repetition period pulse train (PTRI) of the transmitter, for each receiver, determining the phase of the TOA, of each received pulse train in accordance with the PTRI, and the corresponding TOA of each corresponding pulse train, for each receiver, determining the corresponding TOA phase characteristic curves of the corresponding received pulse train, according to the corresponding phase of the received TOA repetitive pulse trains, and for each pair of receivers, determining the transmitter location characteristics according to the TOA phase characteristic curves according to the pulse trains received by each of the receivers.
