Design of Advanced Metric Wave Radar DBF Analog Receiver

Higher performance is required in a modern radar receiver. Digital receiver can meet the needs and it has been an effective implementation method for radar and communication systems. The digital receiver is discussed in this paper, the match of analog receiver and digital module, the calculation and allocation of gain are focused on. A detailed design of analog receiver is presented according to special requirements. The analysis, calculation and detailed design of all units are made, an analog receiver example is developed and the test results are given after debugging. The test results show that the performance of the analog receiver example meet the needs of the design. It has been used in an example system and works stably and well.
