Radar operation in a nuclear-scintillated environment

A system for detecting airborne and spaceborne objects in a nuclear-scintillated environment, comprising:

• a transmitter configured to transmit a plurality of narrowband signals corresponding to a plurality of consecutive segments of a linear frequency modulated (LFM) waveform;
• a receiver configured to receive a plurality of echo signals corresponding to the plurality of narrowband signals being reflected from an airborne or spaceborne object;
• one or more processors;
• memory;
• and
• one or more programs, wherein the one or more programs are stored in the memory and configured to be executed by the one or more processors, the one or more programs including instructions for:
• processing the plurality of echo signals to generate a plurality of waveform segments,
• combining the plurality of waveform segments to produce a composite waveform, and
• applying a matched filter to the composite waveform based on the LFM waveform to detect the airborne or spaceborne object.

A non-transitory computer-readable storage medium comprising one or more programs for detecting airborne and spaceborne objects in a nuclear-scintillated environment, wherein the one or more programs, when executed by one or more processors, cause the one or more processors to:

• cause a transmission of a plurality of narrowband signals corresponding to a plurality of consecutive segments of a linear frequency modulated (LFM) waveform;
• receive a plurality of echo signals corresponding to the plurality of narrowband signals being reflected from an airborne or spaceborne object;
• process the plurality of echo signals to generate a plurality of waveform segments;
• combine the plurality of waveform segments to produce a composite waveform;
• and
• apply a matched filter to the composite waveform using the LFM waveform to identify the airborne or spaceborne object.
