Research On Multi-channel Large Dynamic Ranger Radar Receiver

Radar receiver system is one of the most important sub-systems of Radar, which connects antennas with signal processing system, and which parameter influences Radar performance.There are various processes of design and realization to different types of Radar receivers working in various frequence bands, but wideband, low noise, large dynamic ranger, excellent stabilization characters are commonness basic requirements and development direction to modern Radar receivers. Especially during research and design of receivers of convetional phase-array Radar, the last three points are pivots to determine many design steps, such as chips and modules selecting and combination, circiuts designing, and parameters assigning, ets.This thesis introduced a project work of a multi-channel receiver with large dynamic ranger. The theory, knowledge, and experience involed in the research working are universal and are all helpful and useful to other Radar receiver designer. The thesis also introduced an automatic integrative measuring system, which was designed for the receiver system and had many good characters, such as agility, legerity, credibility, and excellent expansibility.
