Embodiment Construction
[0025] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.
[0026] In order to solve the problem in the prior art that the clutter of radar signals affects communication efficiency, the present invention proposes a method and device for suppressing clutter based on space-time interpolation.
[0027] Such as figure 1 As shown, the method includes:
[0028] Step S101: receiving the space-time signal of the onboard non-frontal array radar, and calculating the pitch angles of different fuzzy range gates corresponding to the lth range gate of the space-time signal;
[0029] Specifically, the echo slope distance of the m-th fuzzy range gate corresponding to the l-th range gate is calculated according to the following formula:
[0030] R ( ...
