数字接收机是数字阵雷达系统的核心模块之一,其性能指标影响整部雷达的目标探测性能。文中介绍一种运用于高机动车载雷达平台的多通道一体化数字接收机,其采用一种全新的小型化、模块化、高度集成化的设计方案。一体化接收机采用收发全数字集成化设计,收发信号形式和波形设计非常灵活;对外接口简单,体积小、质量轻、集成度高,电磁兼容性好,并具备在强振动冲击条件下持续工作的能力。

The performance of digital receiver, one of the core modules in digital array radar, influences the target detection performance of the whole radar. In this paper, a multi-channel integrated digital receiver designed for high-maneuver vehicle system is presented, in which a new design with miniaturization, modularization and integration is employed. The digitization in both receiver and transmitter is adopted in the integrated receiver, which makes the signal form and waveform design flexible. With the advantages of simple structure, small volume, light weight, high integration and good electromagnetic compatibility, the integrated receiver can keep working under the strongly vibrational conditions.
