Problems solved by technology

Such devices are generally divided into two methods: space radiation and direct injection. The simulation of space radiation requires conditions such as shielded darkrooms and array target simulation systems. The large transmission loss of W-band signals affects high-power simulations, and the system is complex and costly. Injection-type hardware-in-the-loop simulation method is simple in structure and low in cost

Abstract

The invention provides a W-band digital sum-and-difference injection hardware-in-the-loop simulation method and device. A W-band frequency conversion module of the device receives the radio frequencysignals emitted by radar, the signals are converted from W-band into baseband signals through a frequency agile local oscillator, five channels of echo signals are converted from baseband signals to W-band signals, and the W-band signals are transmitted to a tested product. An echo baseband signal generation module and an imaging modulation module sample the baseband signals after down-conversionby the W-band frequency conversion module, modulate the echo parameters of a target in the digital domain and generate corresponding imaging echo signals. An inter-channel amplitude-phase consistencycompensation module tests the amplitude-phase error between five channels, and generates a corresponding compensation model. A 5-channel echo modulation module generates 5 channels of echo signals according to the imaging echo signals and other information to simulate the dynamic characteristic of the target. A real-time control module controls the workflow in real time according to the input signals. The ability of the existing hardware-in-the-loop simulation system to realize dynamic simulation of a high-precision imaging target in W band can be expanded.
