Abstract

The development of a model for the second-order bistatic HF radar cross section on an ocean surface patch remote from the transmitter and receiver is addressed. The cross section is referred to as patch scatter. The derivation starts with the second-order normal electric field equation which is in an asymptotic two-dimensional spatial-convolution form, and is accomplished by carrying out the inner convolution before its gradient. The bistatic result is verified by two means: (1) the complete form of the bistatic HF radar cross section in backscattering case is equivalent with the monostatic equation; (2) the bistatic electromagnetic coupling coefficient can be shown to reduce to the monostatic result when backscattering is imposed. The cross section model is also depicted and discussed based on simulation.
