One Method for Target Location Used in a Radar System Based on External Illuminator and Accuracy Analysis
Jie Zhao · Advanced materials research · 2012
An applicable passive location algorithm of target based on single fixed-site illuminator of opportunity is introduced in this paper. The azimuth can be acquired using DBF (digital beam formation) technique and angle-measuring via amplitude comparison. Based on Time Difference of Arrival (TDOA), the distance between the target and the radar station is achievable. Finally, the accuracy of location is analyzed, and the computer simulation results are presented.
