Technologies

Tools and methods in use

A working set for research and prototypes. Names describe techniques and tool classes. Vendor marks are omitted.

Hardware

Programmable logic for deterministic sample processing and hardware-timed control.

Radio

Software-defined radio architectures for programmable RF experiments.

Front end

Acquisition, conditioning and multi-channel receiver considerations.

Algorithms

Detection, filtering, transforms and estimation in simulation and hardware.

Implementation

Hardware description used for FPGA signal-processing designs.

Analysis

Modelling, algorithm trials and comparison against captured or synthetic data.

Platform

Zynq-7000 development board used as a prototype host. Not a Microark product.

Methods

Sample-domain processing shared by DF, TDOA and receiver work.

Transforms

Spectral analysis and frequency-domain stages.

Delay

Cross-correlation methods for detection and time-difference estimation.

Timing

Sample, channel and site alignment before angle or TDOA estimates.

Geometry

Turning timings or angles into a position hypothesis.

Integration

Processor, FPGA and RF combined into a controllable unit.
