“…By applying (12), the pth ( p = 0, 1) levels of the q = 0 beam are then computed ['white' elements in Figs. 2a -Step 4(a)] by setting at the initialisation (Step 3) the shift indexes to σ ( p) = 0, p = 0, 1…”

“…To fit this requirement, array architectures interlacing different functionalities (i.e. 'interleaved arrays') [6,8] have been successfully proposed because of the advantages in terms of flexibility, costs and fabrication complexity of the feeding network as well as the simplicity of the array elements over standard multi-function layouts [9][10][11][12].…”

“…peak sidelobe level (PSL)] usually arises [6,8]. To counteract such an undesired effect, different design techniques [10,12] have been proposed over the years including random techniques [13], stochastic optimisation [6,14] and hybrid approaches [15] (It is worth pointing out that the more recent optimisation techniques such as the artificial bee colony algorithms [16] could be extended to the solution of array interleaving problems (IPs), as well. However, owing to their non-analytical nature, these methods will not be considered in the following.…”

The study presents an innovative ‘almost difference set (ADS)’‐based analytical approach for the design of fully interleaved arrays supporting Q > 2 independent functions on a shared aperture. Such a hierarchical subarraying methodology allows one to interweave, on the same lattice, Q = 2P non‐overlapped arrangements with beam properties a‐priori predictable from the descriptive parameters of the chosen ADSs. A general formulation for the pattern analysis of subarray layouts is derived and successively employed to assess features and potentialities of the multi‐level ‘ADS’ interleaved scheme. A set of representative numerical results, concerned with different apertures, balancing factors and number of interleaved functions, is presented to give some indications on the effectiveness, the efficiency and the reliability of the proposed approach.

“…In order to overcome such drawbacks, several approaches have been proposed [1][2][3] [4] starting from random techniques aimed at reducing the P SL of shared apertures [5]. More recently, stochastic optimization techniques [1] [2] or hybrid approaches [6] have been successfully applied.…”

This paper proposes an analytical technique based on Almost Difference Sets (ADSs) for the design of interleaved linear arrays with well-behaved and predictable radiation features.Thanks to the mathematical properties of ADSs, such a methodology allows the design of interlaced arrangements with peak sidelobe levels (P SLs) only dependent on the aperture size, the number of elements of each subarray, and the behavior of the autocorrelation function of the ADS at hand. P SL bounds are analytically derived and an extensive numerical validation is provided to assess the reliability, the computational efficiency, and the effectiveness of the proposed approach. It is worth noticing that, although without any optimization, such an analytic technique si still able to improve (on average 0.3 dB) the performances of GA-optimized layouts.
