Abstract:

A design making of radar calibration equipment based on digital radio frequency memory (DRFM) technique was presented. The equipment can flexibly accomplish target motion simulation, Doppler frequency loading, target RCS simulation functions and so on. This radar calibration equipment is more practical comparing the calibration equipments using fibre delay. A programmed for settling frequency agility was put forwarded for practical demand. At the same time a mathematics model of typical simulating tactics was brought out. The research results showed that this radar calibration equipment base on digital radio frequency memory (DRFM) had much engineering and realizing values.
