- 模拟DF系统任意入射端信号的入射角和功率
- 最多支持14个相位同步的射频输出端口
The IZT COMINT Simulator assumes the place of the receive antenna and its output signals are directly fed into the receive inputs of the COMINT system. In the control software of the COMINT Simulator the user defines time variant “scenarios”:
- type and content of the emissions
- power
- distance
- relative bearing between receive antenna and each emitter.
The emissions are simulated as if they were re- ceived from the actual antenna system of the COMINT receiver. Phase, amplitude and delay of each individual emission are time variant and matched to the current receive scenario.
Each element of the virtual receive antenna is de- scribed by means of a complex gain and delay function of azimuth, elevation and frequency.
The COMINT or DF system can then be operated freely within its frequency range as if it were in a real world scenario.
