Millimeter wave holographic imaging radar system using single irradiator at center of scan aperture
摘要
Abstract
Mathematic models of the MMW(millimeter ware) holographic imaging radar system respectively using single irradiator at the center of a scan aperture and moving irradiator designed by the PNNL(pacific northwest national laboratory) are created based on the Fresnel diffraction theory. In the models, the relationship between reconstruction imaging quality and transmitting antenna radiation pattern, transmitting distance, target shape and receiving antenna radiation pattern has got described in detail. Meanwhile based on the Fourier optics angle spectrum theory and fast Fourier transform (FFT) algorithm the corresponding simulation programs using Matlab platform, are presented for simulating holographic imaging about both systems. Results show that the system proposed in this paper has a better imaging quality than the one designed by the PNNL not only for the near field safety detection but also for the far field object reconnaissance. Moreover, it has a simpler structure. The model and simulation program provide an assistance for deigning the radar system in practice.关键词
