We present here our numerical model of K-$\alpha $ emission from ultrashort pulse laser irradiated foil targets for the experimental conditions [1]. In our simulations, we use initial plasma density profile calculated by hydrodynamic code for the ASE prepulse target interaction. This profile contains a long subcritical part and we show how this subcritical part may influences fast electron generation and K-$\alpha $ emission from the target.
