Modern radars generally perform all of these MTI techniques as part of a wider suite of signal processing being carried out by digital signal processors. MTI may be specialized in terms of the type of clutter and environment: airborne MTI (AMTI), ground MTI (GMTI), etc., or may be combined mode: stationary and moving target indication (SMTI).
AN/APS-136 I band MTI (Moving Targets Indication) radar for EH-60C AN/APS-137 improved AN/APS-116 maritime surveillance radar Texas Instruments for P-3 Orion, HC-130 and S-3B AN/APS-138 improved AN/APS-125 pulse-Doppler ultra high frequency surveillance radar by General Electric for E-2 Hawkeye
The AN/SPS-48E is capable of providing target range, bearing and altitude information using a frequency-scanning antenna using a range of different frequencies in E band and F band with three power modes: high, medium and low. SPS-48 radars stack multiple beams in a train of pulses at different frequencies.
The ability to counter steep diving missiles was improved with more energy at higher elevations or longer pulse. [ 5 ] : 316–317 SPY-1B(V) is a development of earlier SPY-1B with moving target indication capability incorporated in 1997.
The goal is to find the optimal space-time weights in -dimensional space, where is the number of antenna elements (our spatial degrees of freedom) and is the number of pulse-repetition interval (PRI) taps (our time degrees of freedom), to maximize the signal-to-interference and noise ratio (SINR).

Radar Pulse Train. The carrier is an RF signal, typically of microwave frequencies, which is usually (but not always) modulated to allow the system to capture the required data. In simple ranging radars, the carrier will be pulse modulated and in continuous wave systems, such as Doppler radar, modulation may not be required
The AN/TPS-80 Ground/Air Task Oriented Radar (G/ATOR) is the United States Marine Corps next-generation Air Surveillance/Air Defense and Air Traffic Control (ATC) Radar. The mobile active electronically scanned array radar system is being developed by Northrop Grumman and was expected to reach initial operating capability in August 2016.
The APG-63 was developed in the early 1970s and has been operational since 1973, and was installed on all F-15A/Bs. [1] In 1979, it received a major upgrade and became the first airborne radar to incorporate a software programmable signal processor (PSP), and the PSP allowed the system to be modified to accommodate new modes and weapons through software reprogramming rather than by hardware ...
