除非发射机和接收机之间的距离与目标距离相比很小，否则双基地雷达具有许多与单基地雷达显著不同的特性。其中一些产生了操作上的优势，为部署提供了动力，而另一些仅仅带来了麻烦和费用。本文考虑了与目标距离和相对基线方向有关的基本双基地特性。给出了适当的计算公式，并尽可能用图片与单站雷达进行了比较。所涵盖的主题是(i)在弯曲地球上获得的低层覆盖，（ii）恒定“距离”和回波功率的轮廓，（iii）波束宽度对分辨率单元和允许的脉冲重复频率（PRF）的影响，以及（iv）接收弧的宽度和方向。
Unless the separation between transmitter and receiver is small compared with ranges of interest, bistatic radars have a number of properties which differ significantly from the monostatic equivalents. Some of these produce operational advantages which provide a motivation for deployment, while others merely bring trouble and expense. The paper considers the basic bistatic properties which depend on the target range and direction relative to the baseline. Appropriate formulas are given and comparisons with monostatic radar are made, pictorially wherever possible. The topics covered are (i) the lower-level cover obtained on a curved earth, (ii) contours of constant `range' and echo power, (iii) the effects of beamwidths on resolution cells and the permissible pulse repetition frequency (PRF), and (iv) the width and direction of the receiving arc.
