spreadspectrum
In a normal communication channel, it is often desirable to concentrate the information in as narrow a region of the frequency spectrum as possible in order to conserve available bandwidth and to reduce power. The basic spread spectrum technique, on the other hand, is designed to encode a stream of information by spreading the encoded data across as much of
the frequency spectrum as possible. This allows the signal reception, even if there is interference on some frequencies. While there are many variations on spread spectrum communication, we concentrated on Direct Sequence Spread Spectrum encoding (DSSS). The DSSS method spreads the signal by multiplying it by a chip, a maximal length pseudorandom sequence modulated at a known rate. Since the host signals are in discrete-time format, we can use the sampling rate as the chip rate for coding.

DetectPerformanceinMultistaticRadars
将分布式检测器的概念和雷达联网的性能结
合在一起,从而可以得出在不同雷达布站和不同目标起伏条件下信号检测性能。此性能可以对
雷达布站方法和比较单、多站雷达性能研究都带来益处。
(In the paper, assume that the detection performance (such as detection probability and false
alarm probability) in multistatic radars is given on condition:target movements, fluctuating tar-
gets and different positions of the radars.
