Functions
void	processing::renderWindow (std::vector< ComplexType > &window, RealType length, RealType start, RealType fracDelay, std::span< const std::unique_ptr< serial::Response > > responses)
	Renders a time-window of I/Q data from a collection of raw radar responses.
void	processing::applyThermalNoise (std::span< ComplexType > window, RealType noiseTemperature, std::mt19937 &rngEngine)
	Applies thermal (Johnson-Nyquist) noise to a window of I/Q samples.
void	processing::applyThermalNoiseAtSampleRate (std::span< ComplexType > window, RealType noiseTemperature, std::mt19937 &rngEngine, RealType sampleRateHz)
	Applies circular complex thermal noise using a caller-specified complex-baseband sample rate.
RealType	processing::quantizeAndScaleWindow (std::span< ComplexType > window)
	Simulates ADC quantization and scales a window of complex I/Q samples.
FixedFullscaleScalingResult	processing::scaleToInt16FixedFullscale (std::span< const ComplexType > samples, RealType fullscale)
	Scales complex samples against a fixed full-scale to signed int16 IQ.

Detailed Description

Header for receiver-side signal processing and rendering.

This file contains declarations for functions that perform digital signal processing on received radar signals. This includes rendering raw responses into time-domain I/Q samples, adding thermal noise, and simulating ADC quantization.
