Bistatic Radar, Second Edition
4.3 OVALS OF CASSINI The formal definition of an oval of Cassini is the locus of
the vertex of a triangle when the product of the sides adjacent to the vertex is
constant and the length of the opposite side is fixed [137]. When applied to the ...

It is the locus of constant product of distances from two given points (foci) [25]
where transmitting and receiving stations are located. In other words, the ovals of
Cassini are contours of constant SNR on any bistatic plane assuming the right
side ...

Matrix Iterative Analysis
1.6 As mentioned in the text, the ovals of Cassini, which first appeared in Brauer (
1946), provide an eigenvalue inclusion region for a given nxn matrix A, and, as
mentioned in (1.50) of Theorem 1.24, the union of the Cassini ovals can be no ...

Geršgorin and His Circles
Brauer's name had become synonymous with the ovals of Cassini, but, for
unknown reasons, they are rarely mentioned, even though they are superior (cf.
Theorem 2.3) to the Gersgorin disks. (An exception is the book by Korganoff (
1961).) ...

convergence of the iteration functions (1.3) and (1.4) used to solve (1.1) will
involve two families of plane curves, namely, the ovals of Cassini and the level
curves of sin ...
