MONOPULSE TECHNIQUE IN AIRBORNE RADAR

This paper sums up the investigation on application of the monopulse technique to airborne radar.Some typical airborne monopulse radar systems are discussed, and by taking the amplitude-comparison monopulse technique for an example, some cruxes in the monopulse technique are investigated and the data ensuring the performances of the system are given. The application of the monopulse technique to the angle-measurement and tracking in airborne radar are also described.The factors which influence the accuracy of the angle-measurement and tracking are pointed out and the performance of ECCM of the monopulse airborne radar is analyzed.Furthermore several particular applications of the monopulse technique to multifunction airborne radars, such as air-to-ground ranging, the improvement in angle resolution, terrain avoidance and following, etc. are discussed.Finally, it is pointed out that the main purposes in the application of the monopulse technique to airborne radar are to improve the performance of ECCM and to realize the multifunction of airborne radar by use of the signals in sum and difference beams.
