Current users say it’s a sophisticated Proof of Concept Evaluator
and an interactive Design Feasibility Tool.
Requirements address a wide range of issues including:
- Range and Doppler Ambiguity Analyses
- Resolution, Target Geometries, Pulse Repetition rates
- Signal/Noise and Clutter/Noise Performance Evaluations
- Modes of Operation and Control
- Interfaces, including Timing and Data Formats
- Important System Considerations, Space and Airborne
- Implementation constraints (Antenna Sizing, Data Rate, Power)
With RadarCalc, changes to worksheet inputs are consistently promulgated throughout your design,
resulting in rapid analysis of options and limitations.
RadarCalc is a SOPHISTICATED & INTERACTIVE TOOL that facilitates efficient design decisions.
Its broad utility quickly produces many feasible options. Trade-off analysis is a SNAP! The complex
equations and constraints for multi-mode SAR are built-in, with detailed word and graphic
explanations for all the physics needed to understand and optimize your SAR design. Full telephone
support is provided by noted expert and software designer Walt McCandless.
Extensive on-line help, interactive editing & easy-to-use menus
= immediate productivity.
The following is an example of RadarCalc's worksheets,
to show you the flexibility and sophistication of this
affordable and interactive PC-based software.
