Abstract—A novel algorithm referred as the fast physical optics CTQJ=R"  
(FPO) for computing the back-scattered field over a range of aspect ~L"?C  
angles and frequencies is presented. The computation is performed 9[:TWvd  
in the framework of the conventional physical optics approximation yXCH
Bz6&  
appropriate for the high frequency scattering regime. The proposed ,#j'~-5  
algorithm is, also, directly applicable to fixed angle bistatic X?'pcYSL  
configurations and a variety of single scattering formulations. The {vp*m:K  
method comprises two steps. First, a decomposition of the scatterer 5a5)hmO RB  
into subdomains and computation of the pertinent scattering 1;~|[C  
characteristics of each subdomain. Second, interpolation, phasecorrection [
6\b(kS+  
and aggregation of the scattering patterns of the fN6n2*wr(  
subdomains into the final pattern of the whole body. A multilevel C~04#z_$  
algorithm is formulated via a recursive application of the domain o`Q.;1(Y'  
decomposition and aggregation steps. The computational structure ggy9euWV  
of the multilevel algorithm resembles that of the FFT. The proposed vywpX^KPv  
method is especially .. Q6xA@"GJ
