Joint Design of Transmit Waveform and Mismatched Filter for Suppressing ISRJ Under Spectrum Crowed Environment
摘要
Abstract
In modern electronic warfare,interrupted sampling repeater jamming(ISRJ)poses a substantial threat to pulse compression radar.Additionally,with the increasingly complex and congested electromagnetic environment,the spectrum congestion problem(SCP)faced by radar has garnered considerable attention.To enhance radar detection per-formance in a SCP environment with ISRJ challenge,a joint design method of transmit waveform and mismatched filter is investigated in this paper.Specifically,the objective function is formulated to minimize the transmit signal pulse com-pression integrated sidelobe level and jamming signal mismatched filter output integrated level,and the spectral compati-bility constraint is introduced to facilitate the coexistence between radar and other devices.To align with practical engi-neering requirements,energy constraints and peak-to-average modulus constraints are also incorporated into the model.The resultant problem is non-convex and NP-hard.To address it,an alternating optimization framework combined with a semidefinite programming algorithm is effectively employed.Finally,numerical experiments demonstrate the superior performance of the proposed method.关键词
