Abstract

This contribution describe invention of Magnetometer with protection against detection by electronic counter- measure (ECM) registered by Czech patent office as patent no. 305322.¹ Magnetic sensors are often part of dual use or security instruments and equipment. For this purpose is very interesting to build sensor with is hidden against electronic countermeasure. In this case is very important level and behavior of electromagnetic noise produced by sensor. And also electromagnetic compatibility of electronic devices is the area which significant grows nowadays too. As the consequence of this growth there is a continuous process of making more strict standards focused on electromagnetic radiation of electronic devices. Sensors technology begins to be a part of these issues due sensors bandwidth increasing and approaching to frequency of radio communication band. Nowadays microcontrollers and similar digital circuits are integrated into sensors devices and it brings new sources of electromagnetic radiation in modern smart sensors.
