HTZ Communications and HTZ Warfare continue to evolve, with regular updates introducing new capabilities and improvements across radio network planning, spectrum engineering and analysis. Customers with a valid Maintenance Contract (MC) can access and download the latest software releases through the ATDI CRM.
HTZ v2026.7
HTZ v2026.7 introduces updates across tactical radiocommunications, spectrum management, radar, fixed radiocommunications, calculations and the user interface. Key developments include enhanced radar and wind farm analysis, improved interference reporting and new mission-planning capabilities.
TACTICAL RADIOCOMMS
Path course error visualisation: Now displays circles around each waypoint when a Course Error is defined. The radius represents the radial distance reached by the course-error cone around each waypoint, providing a clearer visual representation of the permitted path deviation.
Mobile mission planning – DF interception analysis: A new option, “Mobile should not be intercepted by activated DF(s)”, supports mission planning where detection by direction finders must be avoided. HTZ calculates the maximum permitted flight height at each location for the mobile to remain undetected by a predefined minimum number of DFs. Calculations can cover the entire map or be restricted to polygons, lines or paths.
SPECTRUM MANAGEMENT
Wind farm radar analysis – aggregated pulses: Wind farm C/N+I and I/N calculations now account for the number of aggregated radar pulses and the Pulse Compression Ratio (PCR). These parameters are incorporated into the SNIR calculation to provide more detailed radar performance analysis.
Global interference reporting: The CSV report now includes a “Cumulated I (dBm)” column. This reports the cumulative power sum of interference levels as interferers are iteratively added.
Wind turbine radiation pattern handling: When “Radiated pattern from Wind turbine parameters” is selected for wind farm interference and radar coverage calculations, the direction of the wind turbine antenna remains fixed rather than being reoriented towards each transmitter in turn.
DF noise floor: The parameter associated with Direction Finder objects now corresponds to the KTBF value.
I/N analysis – reference bandwidth and PFD reporting: This function now includes a user-defined Reference Bandwidth in kHz. Interfering power is also converted to PFD in dBm/reference bandwidth and included in the CSV report.
RADAR
Aggregated pulse parameters: You can now define the number of aggregated pulses within the Radar parameters, which is saved in the .TRX file, supporting subsequent radar calculations.
Automatic radar sensitivity: You can manage this parameter in three ways: using the default radar KTBF value, setting a user-defined sensitivity, or using the new Auto mode to calculate sensitivity automatically.
Radar processing gain: A Processing Gain parameter of between 0 and 255 dB has been added to the radar parameters. It incorporates range and Doppler rejection and is used to calculate effective SNIR for Windfarm C/N+I, SNIR and radar detection probability analysis beyond the radar range resolution.
FIXED COMMS – MW and PMP
Space diversity microwave link import: Generic microwave link imports now include the gains and heights of Space Diversity antennas A and B. Space Diversity mode is automatically enabled when a diversity antenna height other than 0 m is specified.
CALCULATIONS
Symmetrical Flat+Diffraction penetration model: This penetration model is now symmetrical. Propagation losses calculated from point A to point B are the same as those calculated from point B to point A.
INTERFACE
Vector polygon creation: This option allows users to create vector polygons directly by clicking on the map to define each vertex.
Internet connection and WMS streaming: Where no Internet connection is available but a local network is detected, HTZ automatically activates “Pause streaming” in the Map Layer Selector. This prevents attempts to download additional tiles from WMS servers.
Postcode reporting: This field in the CSV report is now treated as a string rather than an integer, improving postcode-format handling.
AI mask prediction model: This model supports the “Export PNG tiles + AI mask predict” function, extending the AI-assisted mask prediction capability within HTZ.
HTZ v2026.8 – Coming Soon
HTZ v2026.8 is currently under development and has not yet been released. Planned updates include further developments to interference analysis, radar and wind farm modelling, vector handling, coverage exports and cartographic conversion.
SPECTRUM MANAGEMENT
Network interference I map: The IRF Network Interference mode computes the interference level, I, at any given point. Where interference exceeds the predefined limit in dBm/reference bandwidth, the resulting map identifies the affected point.
Enhanced wind farm C/N+I and I/N calculations: Wind farm analysis will further refine the calculation of interference received by a radar from wind turbine reflections. Effective interference will account for Pulse Compression Ratio, the number of aggregated pulses and Processing Gain. For C/N+I analysis, the wanted signal received from the target will also incorporate the Pulse Compression Ratio and number of aggregated pulses.
RADAR
Refined radar sensitivity calculations: Radar sensitivity calculations will account for the number of aggregated pulses. In the default mode, sensitivity is derived from the radar KTBF value and the number of pulses. Auto mode additionally considers the required SNIR for the expected probability of detection using the Swerling I model.
INTERFACE
Expanded vector file capacity: A new binary .VECx format will support vector layers containing up to 60,000 coordinates. The temporary .VECx file is created from the .VEC file attached to the HTZ project.
Larger PNG coverage exports: Coverage exports to PNG/PGW will no longer be limited to 30,000 points along the X or Y dimension, supporting larger coverage datasets.
Coverage conversion from dBm to dBµV/m: This function converts the currently displayed 16-bit coverage map in dBm into an 8-bit coverage map in dBµV/m. Users define the required conversion factor according to the transmitting frequency and global receiving antenna gain.
Ain el Abd / Aramco Lambert projection: Cartographic conversion will support the Ain el Abd / Aramco Lambert projection (EPSG:2318). The projection uses the AINELABD grid code and has a stated planimetric accuracy of 18 m.
