Abstract: 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.
