%X This paper presents an area efficient Field Programmable Gate Array (FPGA) based digital design of a processing module for MTI radar. Signal contaminated with noise and clutter is modelled to test the efficacy of the design algorithms. For flexibility of design and to achieve optimized results, we have combined the high-level utility of MATLAB with the flexibility and optimization on FPGA for this implementation. Two- and three-pulse cancellers are chosen for design due to its simplicity in both concept and implementation. The results obtained are efficient in terms of enhanced throughput per Slice (TPA) of 1.146, that is, occupying fewer area resources on hardware while achieving optimized speed. The outcomes show that this design of MTI radar processor has many advantages, such as high processing precision, strong processing ability, real time, and low cost. All these advantages greatly contribute to the design requirements and make it appropriate for the application of high-speed signal processing. 1. Introduction In radar systems, it is often desirable to be able to differentiate between moving targets and those that are stationary. This information can greatly serve operators when the surveillance targets of interest, such as vehicles or aircraft, are located in environments with a high density of traffic, clutter, stationary, and slow moving targets. Fortunately, through the use of digital signal processing, it is possible to extract this information from the system in real time using a Moving Target Indicator (MTI) filter [1]. Modern radar systems have evolving requirements, both in how the systems are designed and how the end user uses the data. This results in design change in electronic systems affecting both the military and commercial design communities, that is, the need for smaller, energy-efficient systems with high processing-power requirements. This makes low power consumption key drivers in most designs of high speed systems. More digital logic also allows designers to make early decisions on actionable intelligence and to meta-tag sensor data earlier for more efficient analysis. These and other emerging techniques will allow for the creation of better radar systems, but each requires additional signal-processing resources. One of these resources is the emerging class of high-performance FPGAs. Moving Target Indicator (MTI) radars are developed and used extensively to detect and follow specific moving targets and eliminate clutters. Processing system in the radar is massive and complex, since it is required to perform at high
