This paper will discuss the design and performance of a recently submitted DNW monolithic sensor, the SDR0 (Sparsified Digital Readout) chip, including different test structures, where both analog (charge amplification and threshold discrimination) and digital (sparsification, time stamping) functions have been integrated inside the elementary sensor, as large as 25μm×25μm.
That is why, an array of such elementary sensors and their responses has to be formed and information from it should be evaluated mathematically using pattern recognition technique.
Moreover, this layer constitutes a communication backbone allowing to spread data collected by elementary sensors on a wide area.
The sensing layer consists of miniature devices, also referred to as elementary sensors, whose role is limited to the following: (a) collecting information about presumably malicious objects, (b) generating real-time events related to the detected targets and transmitting the events towards the closest core sensor, and (c) relaying the events generated by other sensors to the core sensors.
The coding principle is directly related to the received signal at the relay (see Equation (5)), we have y R = H R α m + s + n R. We suppose now that the transmitted messages from the elementary sensors and from the destination are both encoded with a RA code structure [19, 20].
The elementary sensors are integrated into the metallic fasteners structure during manufacture.
To comply with the approach of the light addressed sensor matrix, the induced PV signal of mentioned elementary sensors should noticeably depend on the influence of ambient molecules.
We will suppose classically that N ≥ Q ≥ K, i.e., the destination node has the best capability while some relays are more capable than the elementary sensors.
It makes use of a sensor, which is known as an elementary motion detector (EMD).
