Emplacements And Reconnaissance Radar Random Errors On The Positioning Accuracy

Artillery target-search and gun-pointing adjustment radar is a very important branch in modern radar technology. It has a very important application value in military area. This paper will deeply and systemically analyze the effect of random error on the location accuracy of the artillery target-search and gun-pointing adjustment radar by using simulation method, present an approach to increase the location accuracy.First, this paper will introduce the random factors affecting the trajectory, Kallman filtering method, and the mathematic model that is used to process radar data processing and extrapolate the trajectory.Then, we use a simulation method to create a large number of radar measurement values, produce a quantity of random numbers using computer software and add them to the radar measurement values, We use Kallman filtering method to calculate the location, velocity and trajectory coefficient of the target at the moment of the final tracking point, and use the numerical solving method of differential equation to calculate the trajectory, the location of the hostile artillery or the impact point of its own projectiles, Finally, We calculate statistically the random error of the tracking system and analyze the location accuracy.
