| Phased array radar as an increasingly sophisticated radar system has been spreadingly used in militarian fields and civilian applications, and therefore the confrontation for phased array radar has become a popular research direction. However, given the complexity and punctuality of the phased array radar system, the research and experiment on phased array radar in reality has become very difficult and expensive while the computer simulation technology rises for its convenience, flexibility and economy and reflects its advantages in the radar system simulation.This paper studies the phased array system software simulation and phased array radar resource scheduling and related deception interference performance.1. It studys the principles of radar system simulation, and analyzes of the composition and implementation of the antenna array, radar echo signal generation, signal processing and data processing modules of phased array radar. It completes the design of phased array radar software simulation software, introduces its software structure and running processes.It provides a test platform for the related radar combat simulation.2. It studys the principle of phased array radar tracking data rate self-adaptive algorithm and a simulation analysis is taken to compare the tracking performance of the fixed interval method, the recursive method of and a fixed recursive method.3. It studys two principles of the scheduling algorithms based on the EDF model to establish the implementation models of the time window fixed interval scheduling algorithm and the time window variable interval scheduling algorithm, It compares the performance of two algorithms by simulation. With a low average time shift rate, the time window variable interval scheduling algorithm could make the execution success rate of radar event and the utilization of radar scheduling interval better. In addition, based on the thinking of maximization of time utilization, It proposes a new scheduling algorithm of radar event dwell time segmentation(DTS), and takes a simulation to verify its performance. This algorithm could further increase the efficiency and radar event execution success rate in a scheduling interval.4. It studys two false target deception jamming and the evaluation criteria of interfere performance and it leads to a conclusion verified by simulation. A simulation is taken to analysis the interference performance of the two false targets deception jamming on radar with the combination of radar tracking data rates and resource scheduling algorithms. It proposes a false target jamming strategy against radar resource scheduling for phased array radar system that it causes the radar unrecognized the real target and a deep fall on searching ability of radar, it has achieved some interference effects. |
