Wavelet-Based Adaptive Antenna
Amount: $1,098,419 Topic: A18B-T009
This effort is developing a wideband transmitter (500 kilohertz - 500 megahertz) for military and commercial use. The transmitter defeats antenna size requirements through the use of mathematical methods that fragment the signal in the far field into efficiently radiated components. Therefore, for example, powerful amplitude modulated signals (AM) can be radiated from small devices that are only one meter or less, rather than the 75 meters needed to radiate one megahertz from a quarter wave antenna. Signals are fragmented using time-frequency algorithms that provide signal components to serve as bases or so-called frames (which are redundant signal reconstruction sets). The signal fragments are radiated by wideband, small antennas alternating between basis or frame functions, and generally only two such small antennas are needed. The signal fragments are computed in software that receives the desired AM, FM, or other coded waveform which the user desires to radiate. After power amplification, the fragments are radiated and combine in the far field to reconstruct the longer wavelength signal desired. Because of the wideband nature of the fragment radiators, the far field signal formation occurs close to the transmitter itself.

Analysis and Design of Adaptive Multi-Function Antenna Systems Based on Signal Fragmentation
Amount: $1,000,000 Topic: A18B-T009
We propose an innovative approach to the design of multi-function adaptive antenna systems using signal fragmentation by short pulses (wavelets). It relies on the sampling theory, approximation theory, and numerical optimization; it has passed significant prior testing. The use of short pulses allows the radiation of long waves by small size antennas/arrays, which would otherwise be inefficient. This, in turn, enables performing various diverse tasks, e.g., radar imaging and telecommunications, by the same antenna system. In Phase I, we designed a wavelet-based antenna and optimized it numerically for energy performance while maintaining the desired spectral “purity” of the composite signal. A multi-function system prototype has been fabricated and tested, confirming the theoretically predicted properties of the antenna and its broadband-ness. Phase II work includes non-isotropic antennas, multi-frequency signals, and more comprehensive optimization. The resulting improved optimization technique will be tested, validated, and provided as industrial quality software tool with documentation. Proceeding from CW to AM, FM, FSK, and chirps, we will incorporate the capacity to represent radar and communication codes, optimally trading off between spectral leakage and energy efficiency. Directional antenna prototype will be fabricated and shown to generate the desired signals with minimum error and maximum energy efficiency.

Analysis and Design of Adaptive Multi-Function Antenna Systems Based on Signal Fragmentation
Amount: $149,968 Topic: A18B-T009
We propose an innovative mathematical approach to the analysis and design of multi-function adaptive antenna systems. It uses the idea of signal fragmentation that has passed significant prior testing and employs the methods and results from sampling theory, approximation theory, and numerical optimization. The fragmentation of a signal into a combination of short elementary pulses (wavelets) allows the radiation of long waves by small size antennas/arrays, which would otherwise be inefficient. This, in turn, enables performing various diverse tasks, e.g., radar imaging and telecommunications, by one and the same compact antenna system. During Phase I, we will first consider CW signals. Our key goal is to optimize the energy performance of the array while maintaining the desired spectral ``purity'' of the composite signal and satisfying some additional constraints on its shape (related, e.g., to bounds on the input current rise times). We will then expand into AM and FM signals, including FMCW, chirped pulses, frequency-shift keying (FSK), and Baker codes (e.g., direct-sequence spread spectrum (DSSS) modulation). We will also use the results to design and fabricate an isotropic antenna prototype. Phase II will include non-isotropic antennas (analysis and fabrication), more comprehensive optimization, and development of a well-documented “sharable” software package.
