THE STUDY OF CORRECTION OF THE SYSTEM ERRORS FOR RADAR DBF BASED ON SIMULATION

摘要

In this paper, the effects of the diffrence between the patterns of the array elements, and the mismatches of gain and phase between alt receiver channels, on the antenna pattern in DBF radar are quantitatively analysed With the conclusion that these errors would seriously deteriorate the antenna pattern, a compensation scheme making use of test signal and DFT is proposed, the residual analysed The computer simulation results show that the compensation scheme proposed in this paper is efficient in improving antenna pattern.
