針對一維單脈沖雷達體制，分析了地形目標回波特性；建立了地形跟隨雷達空地測距的幾何關系；利用雷達收發信號，導出了地形跟隨雷達和差接收通道的回波信號表達式，進行了波形模擬，得到了地形跟隨雷達的地面散射產生回波在時域中的特性；根據和差回波特性，闡述了差信號過零點檢測測距的原理和方法及工程實踐中的應用，並給出了真實雷達對外輻射試驗的結果，驗證了文中的模擬。 -
At the same time, the power capacity of the above mentioned antenna is preliminarily analyzed. the results show that in the pass band, their power capacities increase with the frequency on the whole, ranging from 10 ’ s kw to 100 ’ s kw. with the change of the pulse duration of microwaves, the measurement is carried out on the sensitivity of the detectors of the types wb - cd01 and 2087 - 6001 - 00, on the attenuation of the
通過調整微波脈寬，對wb - cd01型、 2087 - 6001 - 00型等檢波器的靈敏度，對2082 - 4137系列和tts系列衰減器的衰減量，對rg - 142型微波電纜的衰減量進行了實驗測定，結果表明:在微波脈寬大於40ns時，檢波器靈敏度基本無變化;當微波脈寬在20 ~ 40ns時，檢波器靈敏度會有一定變化，變化趨勢和程度與檢波器的型號有關;而上述型號的衰減器和微波電纜的衰減量幾乎不受微波脈寬的影響。 -
Considering that : ( 1 ) radar can achieve its basic application of collision avoidance and warning with the only function of ranging ; ( 2 ) under high speed conditions, radar should have lager effective range than that under slow speed, we designed a new easily realizable automotive anticollision radar, which employs centimeter wave and square pulse amplitude modulation
