Abstract
A system and method to separate close targets includes transmitting a pulse sequence and detecting a first target at a first target Doppler frequency based on processed received reflections resulting from the pulse sequence. A nulling pulse sequence designed to null the processed received reflections at the target Doppler frequency is transmitted.
Claims20
A method of separating close targets, the method comprising:
- transmitting a pulse sequence;
- detecting a first target at a first target Doppler frequency based on processed received reflections resulting from the pulse sequence;
- and
- transmitting a nulling pulse sequence designed to null the processed received reflections at the target Doppler frequency.

A system to separate close targets, the system comprising:
- a radar system configured to transmit a pulse sequence;
- and
- a controller configured to detect a first target at a first target Doppler frequency based on processed received reflections resulting from the pulse sequence and to generate a nulling pulse sequence designed to null the processed received reflections at the target Doppler frequency.
