Разработан оптимальный алгоритм оценивания времени прихода MSK-радиосигналов пакетных радиосетей в пространственно-разнесенных пунктах приема разностно-дальномерной системы местоопределения. Произведено сравнение разработанного алгоритма с известными. </p></abstract><trans-abstract xml:lang="en"><p>New results on the recently introduced signal processing methods based on matching pursuit and modified nonlinear chirplet approximation are presented. The optimal estimation algorithm for time of arrival of MSK radio signals of packet radio in area distributed receiving points of range difference position location system is developed. The comparison of developed algorithm with known is performed.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>Нелинейная чирплет-аппроксимация</kwd><kwd>поиск совпадений</kwd><kwd>атомарная функция</kwd><kwd>время прихода сигнала</kwd><kwd>взаимная задержка сигналов</kwd><kwd>корреляционный интеграл</kwd><kwd>разностно-дальномерная система местоопределения</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Nonlinear Chirplet Approximation</kwd><kwd>Matching Pursuit</kwd><kwd>Atomic Function</kwd><kwd>Time of Arrival</kwd><kwd>Mutual Delay of Signals</kwd><kwd>Correlation Integral</kwd><kwd>Time Difference of Arrivals System</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Дубровин А.
