介绍了基于旋转弹丸的ADS毫米波多普勒近程探测系统的组成,建立了某武装直升机的近程探测系统数学模型,并且对探测系统目标回波的时域、频域和STFT时频域进行了LabVIEW的仿真分析。结果表明,该多普勒近程探测系统仿真具有较好的测试性和工程实用性,在理论和工程上都具有广阔的应用前景。
The composition of ADS millimeter-wave Doppler range detection system based on rotating projectile is introduced. A mathematical model of short-range detection system for a helicopter gunship is established, and the time-domain, frequency-domain and STFT time-frequency domain of the target echo of the detection system LabVIEW simulation analysis. The results show that the Doppler short-range detection system simulation has good testability and engineering practicability, and has broad application prospect both in theory and engineering.
