　　本書以軍用戰(zhàn)術(shù)短波和超短波跳頻電臺(tái)為研究對(duì)象。重點(diǎn)研究了跳頻通信中跟蹤干擾檢測(cè)和識(shí)別算法。在此基礎(chǔ)上，研究可有效對(duì)抗跟蹤干擾，同時(shí)兼具對(duì)抗其他典型干擾能力的原理、方法和技術(shù)，保證復(fù)雜電磁環(huán)境下跳頻電臺(tái)能夠正常通信，同時(shí)也可為今后跳頻電臺(tái)的研制和運(yùn)用提供一定的理論參考。本書進(jìn)一步豐富了擴(kuò)頻通信干擾檢測(cè)及自適應(yīng)抗干擾理論體系，具有較高的理論價(jià)值和軍事應(yīng)用價(jià)值。本書聚焦跳頻通信跟蹤干擾檢測(cè)、識(shí)別及抗跟蹤干擾技術(shù)，能夠?yàn)橄嚓P(guān)專業(yè)的科研人員、工程技術(shù)人員以及博士生、碩士生提供參考。
