step-by-step technical analysis based on typical radar equations, the data you provided (RCS, radar types), and open-source performance figures. 1. Assumptions and DataJ-35 RCS: 0.01 m² (conservative: 0.1 m²) Rafale (clean): RCS 0.5 m²; Rafale (with 6 missiles): RCS up to 10 m² J-35 AESA radar: Likely KLJ-7A or more advanced (approx. 200+ km detection for 5 m² target) Rafale RBE2-AA AESA radar: ~200 km detection for 5 m² target J-10C: Not primary here, but its radar is roughly similar to Rafale in class (KLJ-7A, see above).
2. Radar Range EquationRadar detection range (for a given probability of detection) scales as: Detection Range ∝ (Radar Power × Antenna Gain × Target RCS)^(1/4) So, if you know detection range for a reference RCS, you can scale for a new RCS: New Range = Reference Range × (New RCS / Reference RCS)^(1/4)
3. J-35 Detecting RafaleNew Range=200×(510)1/4=200×(2)0.25≈200×1.19=238 km So J-35 can detect Rafale (loaded) at ~238 km. New Range=200×(50.5)0.25=200×(0.1)0.25≈200×0.56=112 km
4. Rafale Detecting J-35New Range=200×(50.01)0.25=200×(0.002)0.25≈200×0.21=42 km New Range=200×(50.1)0.25=200×(0.02)0.25≈200×0.38=76 km
5. Summary Table
6. InterpretationJ-35 will see and lock onto Rafale at much longer ranges—especially if Rafale is carrying missiles externally. Rafale is at an overwhelming disadvantage: it might never see the J-35 before being fired upon. Even if we use the larger RCS for J-35 (0.1 m²), Rafale still cannot detect it until much closer—by which point J-35 can fire a PL-15 (range >150 km). AESA radars are similar class, but RCS difference dominates.
