the basic pulse is often the core item for each radar signal. the complexity level of signals that can be generated ranges from simple pulses for component tests to complex and framed pulse sequences including modulation on pulse (mop). in addition, the length of a test signal is often defined by one or more scans of an antenna. as scans can be quite slow, signal length and therefore required arb memory size is quite demanding and hard to implement with classic concepts. thanks to the realtime sequencing capability of the r&s^®smw200a, ultralong signal playtimes producing hundreds of thousands of pulses combined with frequency and level agility can be achieved with minimum memory requirements.

scenarios consisting of complex radar emitters including antenna diagrams and scans or interferers together with the antenna configuration of receivers can be simulated. the simulator can provide all required signals for simulating the angle of arrival (aoa) of radar transmitters. taking into account a propagation loss model, it provides the rf power levels as they occur in real-world scenarios. this solution is ready for validating state-of-the-art receiver equipment and next generation single-channel or multichannel digital receivers in the lab.

replaying customer-specific pdw lists is an essential feature to enable customers to reuse legacy simulation scenarios that have been created. the customer can define mapping rules in the offline pdw import wizard of the r&s^®pulse sequencer software. customer-specific pdw lists can thus be interpreted and applied to the realtime engine of the r&s^®smw200a baseband hardware. consequently, customers can easily do a technology refresh of the signal generation hardware of their radar simulator and benefit from the excellent rf performance of the r&s^®smw200a without redefining all existing simulation scenarios.in combination with the option smw-k306 multiple emitters, the user can interleave up to 16 imported pdw lists and generate one rf signal. users benefit from a clever algorithm to interleave signals and drop pulses in case they collide, based on an optimized, user defined priority scheme.

the r&s^®pulse sequencer software is not limited to pulsed radar scenarios. it also makes it possible to define radar signals mixed with mobile communications interferers or telecom signal transmitters. this is a perfect solution for testing coexistence of radar systems and telecommunications infrastructure. a wide variety of typical digital modulation formats for radar signals is supported. users can also import their own telecom or radar waveform files and simulate scenarios mixed with signals based on predefined modulation formats. furthermore, the software capabilities can be expanded by using its open plug-in interface.

to relieve test engineers from manually programming time-consuming test cases, the r&s^®pulse sequencer software provides many predefined items that can quickly be combined to create challenging radar test cases. user friendliness has been made a top priority by providing 3d previews and graphical live visualization of configured signals. thus operators can quickly familiarize themselves with the software and profit from the capabilities of the simulator.

the pulse sequencer software is designed to take full advantage of the r&s^®smw200a vector signal generator. it offers a maximum rf frequency of 44 ghz and 2 ghz agile bandwidth. for direction finding test setups, an upgrade path from single channel to multichannel phase coherent test setups is available.
