this program gives detail ides on the addition of noise to the radar signal in matlab...in general a radar signal is corrupted by noise at the time of transmission.

说明：  一种基于RSSI的DV-HOP加权算法，该算法基于节点接收信标节点位置元组时的信号强度（RSSI）对邻居节点间跳数进行加权处理，将节点间的跳数与距离相关联，仿真试验结果证明该加权算法可大大提高定位精度。( a RSSI based weighted DV-HOP (RWDV-HOP) Localization algorithm is presented. In this algorithm the hops of adjacent node is weighted by the RSS of flooding packets transmitted between adjacent node. Our algorithm improves the localization accuracy compared with previous algorithms, which has been demonstrated by the simulating results.)
