Abstract:
Two objective functions used currently for optimum design of low radar cross section(RCS) aircraft are analysed and their shortcomings are pointed out. A new objective, that is, the probability that the RCS of the target in the sector of radar threat exceeds the critical RCS, is proposed based on the relationship between the probability of radar detection and RCS distribution. An example is presented to illustrate that the new objective function proposed by the paper is very useful and effective for optimum design of low RCS aircraft configuration, as well as for the integrated design of aerodynamic and low observable disciplines.
Key words: objective function, radarcross section, detections
