Fabricamos e avaliamos um protótipo de sistema de imagem usando a técnica Simultaneous Frequency-Encoding, que é uma técnica de imagem ativa que é potencialmente capaz de gerar imagens rápidas de frequência de quadros usando uma antena de varredura de frequência com apenas um único transceptor. O protótipo realizou aquisição simultânea de pixels em elevação utilizando Simultaneous Frequency-Encoding e realizou uma varredura mecânica em azimute. Também estudamos uma técnica variada e a incorporamos ao protótipo. A técnica de alcance para Codificação Simultânea de Frequência deve levar em consideração as características da antena de varredura de frequência, que são fundamentais para a Codificação Simultânea de Frequência. Verificamos que o processamento de faixa normal pode ser realizado antes da análise de frequência com codificação simultânea de frequência, fornecendo perfis de faixa e angular. O protótipo foi avaliado com base nos padrões de radiação de uma antena receptora composta por uma antena de varredura de frequência e um refletor, dos quais dependem a qualidade da imagem e o desempenho do alcance. Finalmente, realizamos testes de imagem reais e confirmamos a capacidade de imagens através de obstáculos. A frequência do quadro era de apenas 0.1 Hz, devido ao uso de uma varredura mecânica lenta em azimute. No entanto, assumindo que a formação de feixe eletrônico seja usada em vez da varredura mecânica, a frequência do quadro pode ser melhorada para vários Hertz.

Abstract: We fabricated and evaluated a prototype imaging system using the Simultaneous Frequency-Encoding technique, which is an active imaging technique that is potentially capable of fast frame-frequency imaging using a frequency-scanning antenna with only a single transceiver. The prototype performed simultaneous acquisition of pixels in elevation using Simultaneous Frequency-Encoding and performed a mechanical scan in azimuth. We also studied a ranging technique and incorporated it into the prototype. The ranging technique for Simultaneous Frequency-Encoding must take into account the characteristics of the frequency-scanning antenna, which are fundamental to Simultaneous Frequency-Encoding. We verified that ordinary range processing can be performed before frequency analysis with Simultaneous Frequency-Encoding, giving both range and angular profiles. The prototype was evaluated based on the radiation patterns of a receiver antenna comprising the frequency-scanning antenna and a reflector, on which both the image quality and ranging performance depend. Finally we conducted actual imaging tests and confirmed the capability of through-obstacle imaging. The frame frequency was only 0.1 Hz, which was due to the use of a slow mechanical scan in azimuth. However, assuming electronic beam forming is used instead of the mechanical scan, the frame frequency can be improved to several Hertz.
