| 1 | Product Name | Digital Radar Warning Receiver |
|---|---|---|
| Product Brief | The Electronic Warfare scenario is changing very rapidly. With advances in technology, the radar systems have become more and more sophisticated. The duty cycles of the signals are expanding and power levels are coming down. Intra-pulse characteristics of the pulses are making them more and more difficult to detect by the EW system. To counter this on the other hand, EW system designers are employing Digital Receivers leveraging the advances in analog-to-digital Converters and Digital Signal Processing Techniques. CASDIC has developed such advanced Digital Radar Warning Receiver Dhruti for real time situational awareness. The system would provide versatile solution to a fighter platform offering very good sensitivity, selectivity and wideband instantaneous bandwidth at the same time. Digital Signal Processing techniques are exploited to replace complex RF and analog hardware. These techniques make the detection process more versatile, flexible and powerful against even the most complex radar signatures. Build-on fast response RF hardware, the dynamic Reception regime offers excellent probability of Intercept against variety of radars. | |
| Salient Feature | The system uses frequency domain detection processing based on Digital Filtering that offers very low Effective Noise Bandwidth. Dhruti thus, achieves system sensitivity that would give very good Range Advantage Factor against any kind of emitters. Pulse Density that can be handed is an order of the magnitude greater than the system designed in recent past. The hardware complexity of the system is low-to medium in terms of the size, power and weight. Thus Dhruti is an ideal solution that addresses not only the present but the future challenges also for a fighter aircraft.The system has completed flight evaluation and is in the process of induction to one of the frontline fighters of IAF. |

| 2 | Product Name | Air Cycle Machine Based Cooling system |
|---|---|---|
| Product Brief | The advanced EW systems being developed at CASDIC. Due to lack of internal space, the EW systems will be integrated as podded systems. The Podded EW suite should house a self-contained cooling system for seamless operation of the EW suite. These are self-contained cooling system and only require the basic electrical power from the aircraft for their operation. It generates the cooling air required for taking away the heat from the coolant using the ram air during flight. | |

| 3 | Product Name | PHASE CHANGE MATERIAL HEAT EXCHANGER |
|---|---|---|
| Product Brief | The Phase change material based plate fin heat exchanger is a novel component being developed by CASDIC DRDO. The heat exchanger serves the purpose of providing a backup for a stipulated amount of time when the main cooling system is unable to deliver the required cooling. Hot liquid flows into the heat exchanger and exchanges heat with the Phase change material which gradually melts and changes phase from solid to liquid absorbing the latent heat. The molten material is solidified again and reused. | |
