The Effect of Excitation Errors on the Performance of AESA-Based Cross-Eye Jammers

The excitation errors are unavoidable problems in applications of active electronically scanned arrays (AESAs). At present, the effect of excitation errors on the jamming performance of AESA-based cross-eye jammers and the tolerances for excitation errors are unclear. In this letter, the effect of excitation errors on the jamming performance is revealed. And the tolerances for excitation errors are determined through statistical analysis. The verification results show that the expected performance of AESA-based cross-eye jammers is guaranteed under the proposed tolerances for excitation errors.
