A general result is established for annihilating sets : strongly/weakly annihilating sets for the Fourier transform yield such sets for the ambiguity function, extending a result known for sets of finite measure. We apply this to sublevel sets of nondegenerate quadratic forms. The three-dimensional plot of the ambiguity function versus frequency and time delay is called the radar ambiguity diagram. The auto ambiguity function is defined as χ τ ν τ πν( ), exp 2u t u t j t dt( ) ( ) ( )* ∞ −∞.

Thus, there are two common forms of the ambiguity func-tion: the narrowband ambiguity function, χN,(s∗(t) means complex conjugate of the broadcast signal) χN (ω,τ)= ∞ −∞ e−itω s∗(t)s(t−τ)dt, (2) and the wideband ambiguity function, χWB, χWB (ω,τ)= √ α ∞ −∞ s∗(t)s(α(t−τ))e−itω dt.

The ambiguity function establishes global conditions under which the local bounds are accurate predictions of the expected error performance and identifies the regions of the parameter space where large errors may occur. Ambiguity functions were first introduced by Woodward [13] in active radar. Computing the cross ambiguity function is essential for TDOA/DD emitter location.

function, E, related to the sidelobe energy within the auto-ambiguity and cross-ambiguity functions of a set of complex sequences. For calculating this ‘global’ gradient this section is divided in three parts. The first one gives the gradient equation of the cost function associated to the auto-ambiguity function …

The ambiguity function establishes global conditions under which the local bounds are accurate predictions of the expected error performance and identifies the regions of the parameter space where large errors may occur. Ambiguity functions were first introduced by Woodward [13] in active radar. Computing the cross ambiguity function is essential for TDOA/DD emitter location. Many algorithms for computing the cross ambiguity function have been presented in literature throughout the years.
