Except , the error model of orthogonal modulation and double frequency technology were studied . third , the design and implementation of ultra wide band lfm generator were studied . an ultra wide band lfm pulse compression signal generator with 400mhz carrier and 300mhz absolute bandwidth was developed successful ?第三部分在理論分析的基礎(chǔ)上對(duì)超寬帶lfm信號(hào)源系統(tǒng)的設(shè)計(jì)和實(shí)現(xiàn)技術(shù)進(jìn)行研究,成功研制出了中心頻率為400mhz ,帶寬為300mhz ,重復(fù)頻率為1khz ,脈寬為20 s的線性調(diào)頻信號(hào)。
