摘 要:浮標(biāo)式高頻地波雷達(dá)是一種能夠突破傳統(tǒng)地波雷達(dá)僅能沿海岸線布設(shè)的限制,通過接收天-地混合路徑回波,將探測(cè)范圍擴(kuò)展至遠(yuǎn)海區(qū)域,大大增強(qiáng)雷達(dá)系統(tǒng)部署的靈活性的新型高頻地波雷達(dá)。該系統(tǒng)具有可拓展性,具備進(jìn)一步接納雷達(dá)節(jié)點(diǎn)的能力,為多樣性的應(yīng)用提供了可能,該系統(tǒng)在國(guó)內(nèi)是首次論證并自主設(shè)計(jì),是我國(guó)海洋技術(shù)領(lǐng)域在十二五期間的863重點(diǎn)課題。浮標(biāo)式高頻地波雷達(dá)主要由地波雷達(dá)分系統(tǒng)、浮標(biāo)平臺(tái)分系統(tǒng)、軟件子系統(tǒng)、電源通信運(yùn)管分系統(tǒng)組成,其結(jié)構(gòu)緊湊、功耗低,環(huán)境適應(yīng)性好。通過研究浮標(biāo)式高頻地波雷達(dá)總體技術(shù)、多頻段多通道并行的被動(dòng)相參接收技術(shù)、基于多徑多源信息融合算法反演技術(shù)、運(yùn)動(dòng)與姿態(tài)(多譜勒頻移)補(bǔ)償技術(shù)、圓形天線陣列及其自適應(yīng)波束形成技術(shù)、浮標(biāo)平臺(tái)穩(wěn)定性設(shè)計(jì)技術(shù)、海洋環(huán)境密閉防腐設(shè)計(jì)技術(shù)、電源通信運(yùn)行管理控制技術(shù),并在軟件算法設(shè)計(jì)、浮標(biāo)平臺(tái)設(shè)計(jì)、低功耗雷達(dá)主機(jī)設(shè)計(jì)、雷達(dá)全自動(dòng)化工作等方面進(jìn)行重點(diǎn)突破,基本完成了浮標(biāo)式高頻地波雷達(dá)的研制開發(fā)任務(wù)。目前產(chǎn)品初裝已全部完成,并已完成硬件聯(lián)調(diào),具備進(jìn)行軟件聯(lián)調(diào)及外場(chǎng)試驗(yàn)階段的條件。

Abstract:Buoy HFSWR can break through the limit of the traditional ground radar can only laid along the coastline, by receiving day-mix echo path, the detection range is extended to regions far from the sea, greatly enhancing the flexibility to deploy a radar system. The system has scalability, with the ability to further acceptance radar nodes, provides the possibility for the diversity of applications, this is the first demonstration system in the country and independent design, the 863 subjects in the field of marine technology during the second five. Currently initial product installation has been completed, and has completed the hardware debugging, it has the conditions of software debugging and qualified field testing.
Key Words: Buoy; Radar; Detection; Multiple sources; Multipath
