This paper introduces design and implementation using an FPGA (field programmable gate array) technique of a new method called Maximum Spike Subtraction (MSS) for Constant False Alarm Rate (CFAR) circuit design in radar receivers. The objective of this method is to detect targets accurately in cluttered and multi-interfering target environments. The MSS method depends on selecting the maximum sample amplitude from the input signal sampler and subtracting it from the sum of echo samples in the sliding reference cell window of CFAR. This process provides a more precise estimation of the background noise, which enables the determination of an accurate threshold for target detection. (MSS) the method is evaluated and compared with two significant methods, cell averaged CFAR and ordered statistics (OS)CFAR), to detect targets when multiple targets occur inside a clutter cloud, representing the worst radar environments. The MATLAB clutter test model was used to simulate all of these techniques and apply them to various radar environment instances.
