This paper deals with the problem of robustly reconstructing n -by- n structured matrix signal via convex optimization in random setting. The traditional vector signal model is extended to matrix model. By means of a generalized matrix width estimation and sub-differential analysis, fundamental lower bounds on number of random measurements to guarantee high successful reconstruction probability are established. In comparison with most current works, these bounds are tighter and the methods are more suitable to be generalized to dealing with high-order tensor signals.
