The paper presents a practically realized system of electronic programmable detonator designed for tandem systems. The presented layout was implemented on the basis of micro-controllers using RISC architecture. The detonator is equipped with a fast precursor excitation system and can be programmed for the required delay time of the detonation of the main charge in the range from a few to several hundred µs. The paper presents the results of laboratory preliminary tests of the implemented system. Thanks to the possibility of delay time programming, the system has a wide range of practical applications also during shooting tests.

The article describes the results of laboratory tests of the algorithm of control of programmable detonators designed for tandem systems. Control elements were made on the basis of microcontrollers using RISC architecture. The detonator has a system to quickly excite the precursor charge and can be programmed at any time to delay the detonation of the main charge. The lack of delay in excitation of the precursor charge was realized using a comparator. The article presents the results of preliminary laboratory tests of the control algorithm of the executed system. The flexibility of the solution to program any delay time for the excitation of the main load provides a wide range of practical applications.

The paper comprises the concept of application of low cost devices creating an active interference by emitting low power, which results in an effect comparable to that obtained with the use of expensive high power devices. Modern radars have many mechanisms that increase their resistance to interference, including active ones. In order to address this issue the use of synchronized sources of the interference is proposed. These sources generate signals in specific frequency bands that correspond to the working frequency of the device to be interrupted. The paper describes the concept of creating a dedicated, spatial interference with the use of miniature, microwave oscillators, which are synchronized by a signal intercepted from the device being interrupted.
