內(nèi)容簡介

　　本書以軍用戰(zhàn)術(shù)短波和超短波跳頻電臺為研究對象。重點研究了跳頻通信中跟蹤干擾檢測和識別算法。在此基礎(chǔ)上，研究可有效對抗跟蹤干擾，同時兼具對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)境下跳頻電臺能夠正常通信，同時也可為今后跳頻電臺的研制和運用提供一定的理論參考。本書進一步豐富了擴頻通信干擾檢測及自適應(yīng)抗干擾理論體系，具有較高的理論價值和軍事應(yīng)用價值。本書聚焦跳頻通信跟蹤干擾檢測、識別及抗跟蹤干擾技術(shù)，能夠為相關(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。

作者簡介

　　閆云斌，中國人民解放軍陸軍工程大學(xué)教師，發(fā)表各類文獻近百篇，相關(guān)專利50余項，主要研究方向無人機、跳頻通信、雷達液壓缸。
