本文研究具有一部发射机和N部分散接收机的多基地雷达配置的检测向题。提出了一种时间离散数学结构,使能应用似然比检验。针对斯怀林起伏模型,给出了最佳多基地接收机构造。对此可描述如下:将每一波形馈入平方包络检波器,输出与一个加权因子相乘,(加权因子与本地平均信噪比有关,)然后把计算出的N个量相加并与门限值相比较。为了确定接收机性能,计算出作为虚警概率和本地信噪比的函数的检测概率。
This paper investigates the detection of multi-base radar configurations with a transmitter and an N-partial receiver. A time discrete mathematical structure is proposed to enable the application of likelihood ratio test. According to the Swift model, the best multi-base receiver structure is given. This can be described as follows: Each waveform is fed into a square envelope detector, the output is multiplied by a weighting factor (the weighting factor is related to the local average signal-to-noise ratio) and then the calculated N quantities are added together with Threshold comparison. In order to determine receiver performance, the probability of detection as a function of false alarm probability and local signal-to-noise ratio is calculated.
