Abstract:

For the problem of simulation, evaluation and verification of phased array radar the direction of arrival (DOA) estimation of phased array radar, the modeling and evaluation of phased array radar DOA estimation is discussed. A real-time simulation system based on interactive control is designed. The simulation system can be used to model and simulate the interactive target & environment, phased array and target detection efficiency evaluation model. The signal generation, free space propagation, echo signal acquisition, signal processing and other processes can be simulated during the detection of real-time flying target, and the effect of DOA estimation can be evaluated. Simulation test results verify practicability and validity of the simulation system. The design of this simulation system lays a foundation for the system design, target detection efficiency evaluation, equipment presentation, test and verification of phased array radar in competitive modern warfare environment.

Key words: phased array radar, real-time simulation system, direction of arrival(DOA) estimation, interactive control
