Abstract

The invention relates to a Linux-based radar simulating device and method, belonging to the technical field of radars and solving the problems that the traditional radar simulating device can only be used for detecting a physical path of automatic testing equipment and cannot be used for determining whether software functions and hardware functions of the automatic testing equipment are normal ornot. The Linux-based radar simulating device provided by the invention comprises an emission power supply branch circuit, a servo power supply branch circuit and a receiving system power supply branch circuit, wherein the emission power supply branch circuit is used for outputting a TTL (Transistor-Transistor Logic) high-level signal used for simulating a radar emission branch circuit, the servo power supply branch circuit is used for outputting the TTL high-level signal used for simulating a radar servo branch circuit, one branch circuit of the receiving system power supply branch circuit isused for supplying power to an intermediate-frequency reference frequency source, and the other branch circuit of the receiving system power supply branch circuit is used for outputting the TTL levelsignal for simulating a radar receiving branch circuit. The Linux-based radar simulating device and method provided by the invention are suitable for radar simulation.

Description

technical field [0001] The invention relates to a Linux-based radar simulation device and method, belonging to the technical field of radar. Background technique [0002] Radar is an electronic device that uses electromagnetic waves to detect targets. It is used to complete the measurement of distance, speed, pitch angle, azimuth angle and angular velocity. It is the key equipment for guiding missiles to fly to the target in the entire guidance system. By determining the position of the target, it generates commands to control the aircraft and eliminates flight deviations, so as to achieve precise strikes on the target. Therefore, in the process of developing, producing and equipping troops with radar equipment, advanced testing technology and testing equipment are a favorable guarantee for testing the performance parameters of radar equipment and shortening the development time, and its automatic testing equipment is also an indispensable key in the entire weapon system eq...
