Multifunction radar(MFR)is a large scale dynamical system which exhibits complex signal forms.The problems in deciphering the signals and inferring the MFR's policy of operation really challenge the electronic intelligence(ELINT)society.By drawing lessons from the ideas of gene engineering

the research framework and study methods for MFR signal analysis are proposed.From the viewpoint of system

an analogy is made between the MFR and the organism's cell

which suggests their high level parallelism in system architecture and policy of operation.The key techniques in gene engineering

especially reverse engineering

which can be applied for MFR signal analysis

are summarized

and pre-well-prepared work demonstrates that the proposed method is reasonable.
