Ambiguity Function of Symmetric Triangular Frequency Modulated Continuous Waveform

Waveform Design and Generalized Ambiguity Function for Ultrawideband Nonsinusoidal Signals

The classical theory of radar resolution is based on narrowband sinusoidal waveforms and cannot directly be applied to ultrawideband (UWB) impulse radar. The concept of a generalized ambiguity function, which is a two-dimensional autocorrelation function in the range-Doppler domain, was first introduced by Harmuth in 1981 as a convenient design tool for the performance analysis of carrier-free ...

radiation pattern analysis of frequency diversity array based on square frequency modulated continuous wave

according to high costs of phase shifters in antenna arrays, new methods for beam steering without phase shifter were introduced. frequency diverse array (fda) concept is another approach to beam steering problem. in this structure, the subsequent antenna elements are fed with stepped discrete frequencies causing continuous scanning of space in time. so a range-angle dependent scanning is made ...

Triangular approximations of fuzzy number with value and ambiguity functions

Diagonals of continuous triangular

Diagonals of continuous t-norms are studied. The characterization of all functions being diagonals of continuous t-norms is given. To a given diagonal, the class of all continuous t-norms with this diagonal is characterized.
