This letter focuses on the local ambiguity function shaping through unimodular sequence
design. An accelerated iterative sequential optimization (AISO) algorithm is proposed to …

The ambiguity function (AF), which is used to evaluate the range and Doppler resolutions,
plays an important role in radar systems. In this article, we consider the problems of jointly …

It has been shown in traditional single antenna radar that designing transmit waveform with
an ambiguity function that exhibits low values in specific range-Doppler bins can enhance …

This paper focuses on designing a set of dedicated sequences for Multi-Static Primary
Surveillance Radar (MSPSR) systems. An efficient algorithm to generate a set of unimodular …

It is difficult to design unimodular sequences with both good auto-ambiguity functions (AF)
and cross-ambiguity functions (CAF), due to its nonconvex and higher cardinality property …

This paper considers the problem of designing unimodular sequence with low peak of
sidelobe level of local ambiguity function. The optimization problem is difficult because of the …

In this paper, we discuss the ambiguity function (AF) synthesis problem for unimodular
sequences, which are widely used in radar/sonar and communication systems. Notions of …

This paper deals with the local optimization of the periodic or aperiodic ambiguity functions
of a set of complex sequences by using a gradient method. This optimization aims to locally …

With increased degrees of freedom of the transmitter, coherent waveform-agile radar system
can change its transmission on-the-fly in response to target detection's requirement. This …
