THE PRIMARY EFFECTIVENESS OF RADAR DEPENDS UPON THE STRENGTH OF RADAR CROSS SECTION (RCS) OF A TARGET.

THE PRIMARY EFFECTIVENESS OF RADAR DEPENDS UPON THE STRENGTH OF RADAR CROSS SECTION (RCS) OF A TARGET. THEREFORE, GREAT EFFORTS ARE CONCENTRATED ON THE REDUCTION OF A TARGET'S RCS TO INCREASE ITS SURVIVABILITY AGAINST HOSTILE RADAR. HOWEVER, THIS RCS IS THE ONLY LINEAR PART OF THE GENERALIZED RCS'S BASED ON OUR PROPOSED NONLINEAR RADAR SYSTEM. THUS, THE STUDY OF ITS OTHER HIGHER-ORDER RCS'S IS DESIRABLE TO ENHANCE ITS SURVIVABILITY AGAINST A NONLINEAR RADAR SYSTEM, IF IMPLEMENTED IN FUTURE. AT THE SAME TIME, WITH THIS NEW RADAR SYSTEM IT IS ALSO POSSIBLE TO DETECT AND IDENTIFY A HOSTILE TARGET WITH LOW CONVENTIONAL RCS, IN TERMS OF HIGHER-ORDER RCS'S. IT IS THE PRINCIPAL OBJECTIVE OF THIS PROPOSAL, AS A FIRST STEP, TO EXAMINE THE FEASIBILITY OF MODELLING A MORE REALISTIC NONLINEAR TARGET IN TERMS OF NONLINEAR RCS'S AND IMPLEMENTING AN APPROPRIATE COMPUTER ALGORITHM SUCH THAT THESE NONLINEAR RCS'S MAY BE COMPUTED DIRECTED FROM THE TRANSMITTED AND RECEIVED SIGNALS MORE EFFICIENTLY.
