The search antenna system of the fire control radar increases the performances of fire-control radar through widening the beam broadening in elevation radiation pattern ,and become to shadow antenna,and increases the high frequency amplifier.

This paper introduces the application of Altera EPM7128S device in fire control radar jam emulator.

In order to deal with vacuum electronic gaseous discharge tube’s disadvantages such as high discreteness of electric parameters,short life time,bad mechanical performance and not friendly to environment,an improved Σ/Δ adder for fire control radar is presented,and measurement result in practical application is given.

In order to enhance the movement naval vessel to the gun-pointing radar continuous image water column echo recognition rate,utilized the water column to be related,track algorithms and so on water column movement predict that have realized to per second 80kB the data quantity continual water column echo water column position extraction algorithm.
