  • 摘要: 為了對(duì)短脈沖非相參雷達(dá)信號(hào)進(jìn)行相參處理，該文根據(jù)其信號(hào)特征，建立了參數(shù)化信號(hào)模型。分析了信號(hào)非相參因素，提出了以匹配濾波和參數(shù)估計(jì)為基礎(chǔ)的補(bǔ)償相參處理算法。通過理論推導(dǎo)證明了對(duì)點(diǎn)目標(biāo)進(jìn)行補(bǔ)償相參處理的可行性。并對(duì)距離擴(kuò)展目標(biāo)進(jìn)行了理論分析，推導(dǎo)出其獲得近似的補(bǔ)償相參增益所需要滿足的條件。并通過仿真驗(yàn)證了理論分析結(jié)果。
    Abstract: Based on the characteristics of short pulse non-coherent radar, the parameterized signal model is established. By analysis on the reasons of no-coherence, compensative coherent processing algorithm based on matching filter and parameter estimation is proposed. The rationality of the compensative coherent processing is proved by the mathematical derivation as to single point target. Then, requirement for the range extended target is analyzed in theory, in the condition of approximate compensative coherent processing. Finally, the theoretical analysis results are verified by simulation.
