Working on ultrasonic based water meter which offers different varients of communication standards such as 2W/3W Sensus Communication and Pulse Communication for Data collection by walk through. This module supports LORA/NBIOT based wireless communication also to facilitate data reading, storing and analysing remotely. This module is optimised for ultra low consumption and with 2 small batteries, it is supports till 23 years of module life.My Contribution: - Deriving module specification based on Product specification. - Circuit (Schematics )Design - Design calculations, Power optimisation , Cost optimisation - providing input and instructions to PCB design team. - Suitable component selection - Hardware design document preparation - Test plan and test procedure document preparation - Testing the module functionality - Debugging and failure analysis - LORA platform module design with different band requirements based on region. - Verification and validation of RF parameters - Establishing wireless communication - Supporting EMI/EMC team in product certification

As the number of electronic components keeps increasing with the development of new features in the vehicles, the number of in-car sensors could be more than a few hundred in the near future. The physical wires connecting the ECUs and the sensors could become problematic due to weight, cost & routing of wires. Introducing wireless network in vehicular communication will result in easy installation/interface of any new sensor in a secure network without making separate wire routing and modification in ECU. My Contribution:Most appropriate Frequency Band selection for IVN.Selecting the technology for establishing communication.Selecting suitable components & designing the module for IVN.PCB Design, Document preparation, Module Testing, Verification & Validation.Proto clearance and production support.

It’s a warfare system which will be used for detecting, jamming and tracking the enemy targets as well as communicating with the base stations and nearby stations in the mountain terrain. It is integrated communication and Non-communication systems. The main objective of CC NC is to carry out the actual EW operations by command, control and supervision of all the Non Comn segment front-end entities and provide the status and results to the CCC/CP. The CC-Com segment deals with voice and data signals. It issues the commands for search, intercept, Jam, DF, LF etc. during operation.You

Project 1PSR ,it’s a costal surveillance radar, typically consists of a standard and advanced solid state radar operating in X-Band (9.3-9.5 GHz). In order to launch sounding rockets, the impact zone of the same needs to be cleared. To meet this requirement, Primary Surveillance Radar, with detection capability of medium sized ships up to a distance of 100km, has been designed..It is capable of detecting small boats (10 meter square RCS) as well as large boats up to a wide range whilst also meeting target separation and accuracy parameters. PSR is required to ensure the target types can be detected and tracked in the designated area covered by the vessel traffic service, taking into account the visibility, sea state and propagation condition relevant for the individual radar site.My Contribution:Radar Calculation including range detection capacity, fading effects, atmospheric attenuation etc.System design (Mostly RF Section)Designed Synthesizer module for providing LO signal for two stage down conversion and up conversion.Designed BITE Module for simulating the receiver chain over the dynamic range (i.e 90dB).Designed X4 multiplier module for tuning the LO signal over the bandwidth (200 MHz)Design up gradation for existing down converter module and up converter module as per project power level requirements.Documents preparation such as Acceptance Test Plan, System requirement document, Test procedures and Test reports for the newly designed modules.System components selectionTechnical Support the software and mechanical team.Module level testing and debugging.Integrated Radar testingModule level as well as system level failure analysis
