Aiming at the problem that it is difficult to carry out functional tests such as fusion data processing and situation fusion display due to the lack of sea-aero target intelligence data before the intelligence processing system is put into use,the demand for simulation environment of the intelligence processing system during the test command process is analyzed,and the overall design idea of the architecture and function model of the sea-aero target intelligence software system is proposed.It adopts the technical method of moving track simulation based on target characteristics and using noise processing to compensate the error of the generated information,which realizes the target track simulation and makes the simulation information more fit the detection equipment to the target observation in the real environment.The practical application verifies the feasibility of the technical method and the flexible applicability of software simulation.

In digital array radar (DAR), channel mismatch has a serious impact on many indicators such as low sidelobe beamforming, signal to interference ratio of output signal and anti-interference. To correct the error, the channel equalization technique is gradually applied to the array error correction and has been rapidly developed. The current channel equalization techniques are divided into time domain least square fitting method, frequency domain least square fitting method and Fourier transform method according to the equalizer weight coefficient solving method. The main principles and difficulties of each method are analyzed emphatically, and the advantages and disadvantages of various methods are compared. The difficulties of the digital array radar channel equalization technique in future development are summarized.
