Plume Attenuated Radar Cross Section Code: User's Manual

The PARCS CODE calculates the coherent, incoherent, and overdense surface radar cross sections of a rocket plume. The modified Born approximation calculation includes attenuation, local index of refraction, Doppler shift and range cell truncation. The program accepts plume data directly from the AeroChem LAPP code, but may be interfaced with other sources of plume definition.
