Description

technical field

[0001] The invention relates to the technical field of radar signal processing, in particular to a double-sideband frequency diversity array radar system and a target positioning method thereof. Background technique

[0002] Radar target detection technology has a wide range of application requirements in both military and civilian fields. Phased array is widely used in radar target positioning, but because its beam pattern is only related to angle, the target distance information cannot be directly extracted from its beam pattern, and the distance-dependent interference and clutter cannot be effectively suppressed.

[0003] The frequency diverse array (FDA) depends on the beam pattern of both distance and angle, making it a research hotspot of domestic and foreign scholars in recent years. However, due to its inherent distance and angle coupling, the distance and angle information cannot be directly extracted from its beam pattern. In addition, the current...
