Abstract

Aimed at the performance testing of amplitude and phase in outfield for T/R modules on active phased array radar, a test scheme on T/R modules based on mid- field measurement technique is presented, and the test system is accordingly developed. The test system takes full advantage of own resources of the radar, and applies the relative measurement of amplitude and phase based on normalization and array unit weighting to analyze collecting data. As a result, the absence of standard data is avoided, the flexibility and adaptability in outfield measurement is greatly improved. Theoretical analysis and measurement results show that the testing system has many advantages, such as simple operations, rapid fault location and lower site requirements. It is proved to achieve a kind of adjoint testing support methods at a low cost.
