Code Design for Moving Target-Detecting Radar in Nonhomogeneous Signal-Dependent Clutter

Abstract EN

In this paper, we investigate the code design problem of improving the detection performance of a moving target in the presence of nonhomogeneous signal-dependent clutter for moving target-detecting (MTD) radar systems.

The optimization metric is constructed based on the signal to clutter and noise ratio (SCNR) of interpulse matched filtering.

Under the frameworks of cyclic and majorization-minimization algorithms, we propose a novel algorithm, named CMMCODE, to tackle the code design optimization problem in the case of unknown precise target Doppler information and nonhomogeneous clutter.

In the white-noise case, the simplified algorithm is also given based on CMMCODE algorithm.

The presented algorithm is computationally efficient and convergent.

Numerical examples show the effectiveness of the proposed algorithms.
