Radar Cross Section (RCS) computation and analysis are carried out for a high speed, kinetic energy missile at 35 GHz. The radar cross section simulations were performed under bistatic conditions, using a 3D Electromagnetic field solver. RCS values for standard geometries such as cylinder, cone -cylinder combination are calculated under different excitation conditions and the results are verified with literature, so as to fix the settings in the solver. A maximum RCS value for the missile is obtained as −4.9 dBsm under broad side excitation. RCS values of −22.25 dBsm and 4.94 dBsm are obtained for 0 • (Nose cone) and 180 • direction, when excited in the frontal region, i.e., 0 • azimuth and 0 • elevation. Further, monostatic simulation under 0 • to 180 • excitation shows a large RCS value of −4 dBsm at 90 • , corresponding to large surface area of the missile. The effect of frequency on the RCS of the missile is also determined in 30 to 40 GHz band. A comparison of integral equation solver and asymptotic solver for RCS computation indicates almost similar values, with a deviation less than 5 dB in most of the ranges. However, with compromise on accuracy, the asymptotic solver is found to consume only 5% of the total time required by integral equation solver.

Precise inflight antenna pattern should be known for synthetic aperture radar (SAR), so that an image pixel intensity is directly expressed in terms of the mean surface backscatter coefficient. For bistatic SAR (BiSAR), in which the transmitter and receiver are mounted on separate platforms, conventional passive calibrators are not applicable any more. As such, an approach is described on how to determine the inflight antenna patterns for BiSAR systems in this letter. This technique is suitable for high-resolution SAR due to the very high dynamic range. More importantly, this technique uses signal encoding to decouple the transponder from the background, which greatly improve the measurement performance. Theoretical analysis and simulation results also demonstrate its validity.
