Abstract:

This paper analyzes the basic principle of the three-dimensional Crossing Location,and derives a quantitative expression of location error.For different direction finding systems,such as amplitude comparison direction finding and interferometer direction finding,the relationship between the carrier frequency of radiation and angle measurement accuracy is analyzed,and then a quantitative relationship between the carrier frequency of the radiation source and the location error is established.The simulation analysis shows that the detected can increase carrier frequency to avoid being located precisely,which has application value.

Key words: direction-finding crossing location;carrier frequency of radiation source;location error
