This paper analyzes the link connectivity probability and the full connectivity probability of the network in a one-dimensional scenario for the man-portable tactical Ad Hoc radio station. By taking Monte Carlo and network simulation approaches，the network deployment and business operations are simulated. The analysis and experimental results show that: the connectivity probability of a typical Ad Hoc radio network gets the minimum value near l/τ；in a large-scale Ad Hoc network，there exists a 0-1 phase transition between the network full connectivity probability and the node communication range；the number of nodes required to achieve a high probability connected network is much less than that to achieve a full connected network.
