Um radar de resolução multi-range usando energia do espectro de banda lateral é investigado. O sistema básico consiste em um processador de afiação e filtros de modelagem de energia com menos erros. Primeiro, o processador de afiação afia pulsos longos e planos. Em seguida, os filtros de modelagem com menor erro comprimem o pulso de entrada na largura de pulso desejada. Então, a largura do pulso de saída pode se tornar mais estreita do que o recíproco da largura de banda de entrada, porque os filtros de modelagem com menor erro fazem com que a largura de banda equivalente seja expandida pelo aumento da energia do espectro da banda lateral e pela supressão do espectro principal. Os sinais transmitidos com modulação de fase simples são estudados para obter a resolução multi-faixa onde o pulso é comprimido em um pulso com a mesma largura de banda e outra largura de pulso igual ao recíproco da largura de banda de entrada. A relação pico-lóbulo lateral após a compressão do pulso e o fator de melhoria da relação sinal-ruído de saída são medidos. Além disso, os resultados experimentais são mostrados para verificar a técnica proposta.

Abstract: A multi-range resolution radar using sideband spectrum energy is investigated. The basic system consists of a sharpening processor and least-error energy shaping filters. First, the sharpening processor makes long flat pulses sharpened. Next, the least-error shaping filters compress the input pulse into the desired pulse width. Then the output pulse width can become narrower than the reciprocal of the input bandwidth, because the least-error shaping filters make the equivalent bandwidth expanded by the enhancement of the sideband spectrum energy and the suppression of the main spectrum. The transmitted signals with simple phase modulation are studied to obtain the multi-range resolution where the pulse is compressed into a pulse with the same bandwidth and another pulse width equal to the reciprocal of the input bandwidth. The peak-to-sidelobe ratio after the pulse compression and the improvement factor of the output signal-to-noise ratio are measured. Further, the experimental results are shown to verify our proposed technique.
