A NEW CONSTRUCTION METHOD OF SPATIAL-TEMPORAL CORRELATION IN SEA CLUTTER SIMULATION

The simulation of spatial-temporal correlated sea clutter returns is of great significance in the research of radar detection and performance analysis. Traditional simulation methods generally introduce a recursive formula into the Spherical Invariant Random Process (SIRP) method to build the Spatial-temporal correlation properties of the sea clutter. However, the methods are computationally intensive and inefficient due to the recursion. In this paper, an efficient construction method of spatial and temporal correlation is proposed for the first time. The new method has reduced the computational burden and became parallelizable. The simulation results have been analyzed in this paper, which show the feasibility and accuracy of this method.
