l.n this paper, the performances of constant falsealarm rate (CFAR) burst detection schemes are analyzed and compared for a communication system which employs constant modulus modulation format and a typical time division multiple access (TDMA) protocol, The burst detection probabilities are derived to incorporate the received signal quality measure which can be expressed as a function of cross...

The uniqueness theorem for ambiguity functions states that if waveforms u(f) and u(f) have the same ambiguity function, i.e., X%(‘S, A) = X.(‘S, A), then u(f) and u(f) are identical except for a rotation, i.e., u(f) = e%(f), where ;i is a real constant. Through the artifice of treating the even and odd parts of the waveforms, denoted e(f) and o(f), respectively, correlative results have been ob...

In this contribution we consider the popular widelaning technique from the viewpoint of ambiguity decorrelation. It enables us to cast the technique into the framework of the least-squares ambiguity decorrelation adjustment (LAMBDA) and to analyse its relative merits. In doing so, we will provide answers to the following three questions. Does the widelane decorrelate? Does it explicitly appear ...

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 ...

The radar ambiguity function represents the output of the matched filter, and it describes the interference caused by the range and/or Doppler shift of a target when compared to a reference target of equal RCS. The ambiguity function evaluated at is equal to the matched filter output that is matched perfectly to the signal reflected from the target of interest. In other words, returns from the ...
