摘　　要：提出了一种新的干涉仪测向处理技术———基于PLD硬件处理的数字式多基线干涉仪测向技术,对高速带通欠采样、数字鉴相、数字测频及解模糊算法等相关的技术进行了详细的阐述,最后给出了工程样机性能测试结果,并与国内外相关设备的技术性能进行了对比。A new processing technique of DF using digital multi - baseline interferometer based on programmable logic device（PLD）is presented in this paper. A brief introduction of its operational principles and implementation is also given herein. The key techniques, such as high speed bandpass undersampling, digital phase discriminator（DPD）, digital frequency measurement and new algorithm for ambiguity solution are detailed. And the test result of performance of the engineering prototype is given finally, and compare it with similar products abroad.
