Because the length of a transponder code train is about 20 µs it is not always possible to decipher replies from aircraft closer than 2-3 miles of each other on a radial from the interrogator. The reply signals may garble and the decoder equipment can cause the generation of false targets between the aircraft or cause cancellation of all or part of either or both actual returns. False targets or cancellation may occur even though altitude separation between aircraft exists. Circuits in the decoder equipment are used to cancel garbled replies, and controllers will often ensure that only one aircraft within a formation has a transponder operations
On a military map it can stand for Secondary Surveillance Radar, Surface Search Radar, Search & Rescue Region, or Soviet Socialist Republic.
Aerostat radar is a low-level surveillance system that uses aerostats (moored balloons) as radar platforms.

The MSTAR is the Man-portable Surveillance and Target Acquisition Radar. It is an all-weather battlefield Doppler radar that operates in the J band.
Sensor surveillance using RADAR (Radio Direction And Ranging), which is a non-cooperative location system, often producing maps of reflected power intensity arranged in range and direction to provide a plan view of the surveillance area.

the primary radar mostly we used for air traffic control and other civil society work but this primary radar will not cover the whole requirement data. But secondary radar system will give all the details which we required Also mostly we used for it for security purpose and we can take the IFF and SSR from this secondary
To detect, track, and sometimes identify objects via the emission of radio waves. Speed radar (like those used by police) can detect nearby objects and calculate their speed. Weather radar can detect the location of clouds and rain. Air traffic radar can detect and track unidentified flying objects. With the help a monopulse secondary surveillance radar, the radar system can identify the individual planes. Higher technology radars can detect and identify distant small objects with great precision.
