A Simulation Method of Digitized Angle Surface Target

Abstract

The invention relates to a method for simulating a digitization angle area target. According to the method, an analog signal is converted into a digital signal, and angle information is debugged through the digitization method so that the simulation of the angle area target can be achieved. By means of the method, angle area target signals comprising a plurality of pieces of angle information can be output from the same channel, cost is reduced, the debugging workload is reduced, and the reliability of a system is improved.

Description

technical field [0001] The invention relates to a semi-physical simulation technology, in particular to a digital angle surface target simulation method. Background technique [0002] In the existing hardware-in-the-loop RF simulation technology, the angle simulation is usually realized by means of array antenna triplets. The three adjacent antennas on the array antenna form a triplet, and the signal of the test is simulated by the signal radiated by the triplet, and the radiation direction is facing the equipment under test. Movement of the radiated signal within a triplet, or from one triplet to another, represents movement in the angular position of the target. [0003] In the prior art, analog signals are often used for angle simulation, and the use of analog signals to achieve angular position control requires maintaining a strict phase relationship among the three channels A, B, and C of the triplet, which is easily affected by the ambient temperature. In addition, e...

Problems solved by technology

[0003] In the prior art, analog signals are often used for angle simulation, and the use of analog signals to achieve angular position control requires maintaining a strict phase relationship among the three channels A, B, and C of the triplet, which is easily affected by the ambient temperature. In addition, each triplet can only output a specific angle in the control of the antenna array. In order to achieve the target of the angle plane, multiple triplets need to be combined. This method has many disadvantages: ① In order to achieve complex goals, multiple Channels, for example, a target model with 10 scattering points requires 10 channels, which increases the cost; ②The synchronization relationship between multiple channels is difficult to achieve, and the adjustment workload for amplitude and phase balance is extremely huge
