An Analysis of Radar Detection on a Plasma Sheath Covered Reentry Target
IEEE Transactions on Aerospace and Electronic Systems, 2021The plasma sheath will be generated on the surface of the reentry object due to the effect of aerodynamic thermoionization, causing multicomponent signals with Doppler frequency components in the radar echo.

Recently, various algorithms for radar signal detection that rely heavily upon complicated processing and/or antenna architectures have been the subject of much interest. These techniques owe their genesis to several factors. One is revolutionary technological advances in high-speed signal processing hardware and digital array radar technology. Another

Radar echoes from the martian satellite Phobos provide information about that object's surface properties at scales near the 3.5-cm observing wavelength. Phobos appears less rough than the moon at centimeter-to-decimeter scales. The uppermost few decimeters of the satellite's regolith have a mean bulk density within 20% of 2.0 g cm

Radar photographs of thunderstorms and the Florida hurricane of September 1945 were shown to illustrate structure of those storms (see Fig. 1). The relation between radar echoes and the reflecting material in the storms was discussed. Previous research has shown the intensity of the return radiation, among other things, to be proportional to the number

We analyze the performance of a radar in an environment where clutter is constituted by discrete scatterers whose radar cross-sections are comparable to that of the target.

A Review of Radar Detection Fundamentals
IEEE Aerospace and Electronic Systems MagazineThis article presents a review of the radar detection literature, which permits engineers to size radar systems considering various fundamental parameters. The monostatic radar equation is reviewed in detail and its different terms are explained.
