Precision Analysis of Loffelds Bistatic Formula (LBF) for Constant-offset Case

Precision analysis of the bistatic spectrum is the precondition of designing imaging algorithms. For the constant-offset case, the precision analysis of the spectrum is given in detail in the frequency domain. The spectrum is exactly analytical when the restrictions of the bistatic angle and the baseline to range ratio are both met. Neither the baseline to range ratio nor the squint angle is a constraint explicitly. Experimental results validate the accuracy of the discussion about the restrictions of the spectrum.
