Abstract

The present invention relates to the technical field of electromagnetic signal processing, and specifically discloses a time-domain positioning system and method for a pulsed radiation source. First (by using a ratio-amplitude direction-finding module) the pulse radiation source is roughly direction-finded through the ratio-amplitude direction-finding module, and given (Traveling module) An initial guidance in the direction of movement guides the entire time-domain positioning system to move non-tangentially and non-radially relative to the pulse radiation source; The pulse arrival time of the radiation source; finally, (using the calculation module) to locate the pulse radiation source through time-domain calculation, which can greatly improve the accuracy of the direction finding compared with the amplitude, and at the same time realize the ranging function of the pulse radiation source. On the premise of not increasing hardware resources, the system can improve the angle measurement accuracy to 1°R.M.S, reaching the level of the correlation interferometer direction finding method, and at the same time realize the ranging function of the pulse radiation source, which can realize the miniaturization of the positioning system , Low cost.

Description

technical field [0001] The invention relates to the technical field of electromagnetic signal processing, in particular to a time-domain positioning system for a pulsed radiation source and a time-domain positioning method for a pulsed radiation source. Background technique [0002] At present, to realize the positioning of the pulsed radiation source, it is necessary to use the precise direction finding technology of the interferometer. Through the movement of the interferometer, the precise direction of the radiation source is measured at different positions to achieve single-station positioning. Interferometer direction finding technology consumes a lot of hardware resources and cannot be miniaturized and cost-effective. Contents of the invention [0003] The invention provides a time-domain positioning system and method for a pulsed radiation source, and the technical problem to be solved is: how to realize the positioning of the pulsed radiation source in a miniaturiz...
