Three-pulse MTI without blind speeds

An MTI with no blind speeds which compensates for antenna scan modulation. This design includes circuitry for generating and transmitting consecutive first, second and third doppler-tolerant FM pulses, wherein the first and third FM pulses have a given dispersion characteristic, and the second FM pulse has a dispersion characteristic which is the complex conjugate of the first and third FM pulses. Circuitry is then provided for receiving and compressing the first, second, and third echos from the first, second, and third pulses, respectively. Finally, a processing circuit is used to effectively add the first and third echo pulses and to subtract twice the second echo pulse from this sum to effect the detection of the moving target.
