KOR Electronics manufacturers many varieties of RES products that are DRFM based or DSP/Synthesizer based and using several different signal processing technologies allowing KOR Electronics to tailor the best available technology to each customer’s specific requirement. The RES output may be an RF, IF, or Digital I & Q signal direct injected onto the radar bus, or it may be transmitted as a Free Space output. These Direct Inject simulators have been developed to be generic to support multiple types of radar systems. The RES systems are used for applications ranging from Anechoic Chamber and Open Air Range (OAR) to laboratory based Radar Production Testing and Comprehensive Radar Performance Evaluation.
