- Abstract
- This paper proposes a new image formulation algorithm using the method of
compressive sensing in an FMCW radar system. This algorithm contains of two
important points. First, we reduced dimension of a sensing matrix using properties of Kronecker product. Second, we adopted a sparse recovery problem on total
variation domain and solved our problem using the Split Bregman method, which
is applicable to 2-D optimization. Thanks to proposed algorithm, we shortened
the time of image formulation and reduced a computational complexity in the
FMCW radar system. As a result, it is expected that a real time SAR imaging
system can be realized.
