 Introduction
The STAP’s theory was published by Lawrence E. Brennan and Irving S. Reed in the early 1970s. Space-time adaptive processing (STAP) is a signal processing technique which is most commonly used by radar systems. Radar signal processing benefits from STAP in areas where interference is a problem (i.e. Ground clutter, jamming, etc.). It is very easy to find the target using this method. STAP uses a two-dimensional filtering technique using a phased-array antenna with multiple spatial channels. To implement STAP an antenna array is used, over a several pulse repetition intervals. The output of this is a linear combination or weighted sum of the input signal.

Basic Concept of how it works
Here the signal is broadcasted all over. When it detects the object signal is sent back to the antenna and this way the object is detected. It is same as the person speaks some words in well and echo comes back with the same words. This way signal come back with some information about the object. RADAR CLASSIFICATIONS
1. Classification based on specific functions

Primary Radar:
High-frequency signals are transmitted toward the targets. The transmitted signal is reflected by the target and then received by the same radar.
