RadarSim 3.0.1

RadarSim 3.0.1 is a maintenance and stability release resolving scenario execution edge cases, dynamic parameter synchronization, and command-line scenario loading.

Highlights in 3.0.1

  • Scenario-Bundled Distribution: Bundled the scenarios/ directory in release ZIP/TAR.GZ archives so standalone executables have immediate access to all 10 scenario definitions.
  • Built-in Scenarios Menu: Added File > ⚡ Built-in Scenarios menu for instant one-click scenario launching without manual file browsing.
  • Rendering Performance Optimization: Pre-cached discrete brush palettes for phosphor persistence trails and affiliation markers, eliminating on-the-fly QPainter rasterization bottlenecks and dropping phosphor update latency from 117 ms to 0.5 ms (192x speedup).
  • Sub-1GHz Attenuation Safety: Guarded ITU-R P.676 atmospheric absorption and ITU-R P.838 rain attenuation for frequencies below 1.0 GHz (such as UHF/VHF early warning radars), applying negligible 0.0 dB attenuation rather than raising an out-of-domain exception. Resolves crashes in stealth_deep_penetration.yaml.
  • Terrain Type Normalization: Added "mountain" alias and normalization in ClutterModel.ground_clutter_sigma0 to match scenario specifications. Resolves crash in mountain_ambush.yaml.
  • Dynamic Radar Parameter Synchronization: Converted SimulationEngine._radar_params to a real-time property synchronized with self.radar, ensuring GUI frequency/power slider changes immediately affect SNR and detection calculations.
  • Command-Line Scenario Loading: python run_gui.py [scenario_path] and radarsim [scenario_path] now accept a scenario YAML/JSON file path directly on startup.
  • GUI File Filter: Added *.json to QFileDialog scenario open filter alongside *.yaml/*.yml.
  • Public Scenario API: Added MainWindow.load_scenario(filepath) for modular and programmatic scenario loading.
  • Windows Console Encoding: Replaced Unicode arrow and lambda characters in console logging to prevent UnicodeEncodeError on CP1252/CP1254 environments.
  • Automated Verification: Added regression tests executing multi-step simulation on all distributed scenarios. Full test suite: 343 passing tests.
