| Passive location technology, which does not radiate electromagnetic wave, can locate the radiant in a hidden way. Featuring in long function range, high anti-interference capacity, it plays more important role in improving survival and operation capacity of electronic system in the electronic war.With the development of modern signal processing techniques and means of measurement, the traditional multi-platform location system may be used in simple and flexible single platform such as satellite and aircraft to achieve the purpose of fast and accurate location. in this paper, the traditional long baseline multi-platform time difference of arrival (TDOA) and frequency difference of arrival (FDOA) passive measurements have been used in the single platform for multi-receiver short baseline case and the principles and location algorithms of TDOA and FDOA measurements have been discussed as well as the location performance of TDOA and FDOA location systems have been theoretical analyzed and computer simulated, further, the best receiver configuration has been obtained. Finally, the two kinds of measurements have been combined and theoretical analysis and computer simulation of joint location has been performed. |
