ABSTRACT
With the development of electronic warfare, the radar signal environments are getting more
complexity, and the simulation on radar environments is necessary to be developed. Also, with
the usage of advanced electronic warfare technology on frequency measurement receiver, a good
many trial data about frequency measurement results are needed in the design and evaluatin
field. It is a good method to get these data by simulation. So, it is a very important problem to
simulate the frequency measurement receiver cooperated with the signal environments
simulation on the platform of HLA
Three sections are consisted in this thesis. In the first section. the typical signal
environments of electronic warfare are discussed. and the traditional methods of simulation on
signal environments are introduced. Then, a kind of new model of signal environment
simulation is illuminated in this paper, and the simulation results based on this model are
expresser
In the second section, a new method of simulation on frequency measurement receiver is put
forward and the simulation model is illuminated by the example of superhetrodyne receiver. And
the evaluating results based on the simulation are given
In the third section, the cooperating simulation of signal environments and frequency
measurements based on the platform of HLA is introduced with the background of a
projection. And the results of the simulation are given
In the last, the thesis also puts forward some problems to be studied in future
