/* The chirp design for the MRR TI design is as follows.
 *
 * The Radar operates in two modes - essentially two subfram-
 * es per frame, with alternate subframes belonging to one of
 * the two modes.
 * 1. A low range-resolution (30cm), high max range (80m),
 *      high max velocity(55kmph), poor angle resolution medium
 *      range radar (MRR) mode - called the MRR80 mode.
 * 2. A high range-resolution (4.5cm), low max range (20m)
 *    low max velocity (18kmph), high angle resolution ultra
 *    short range (USRR) mode - called the USRR20 mode.
 *
 * However the max velocity of 80m is not enough for the MRR
 * use case, and we need to facilitate algorithmic techniques
 * to improve it. We will create two kinds of chirp in the
 * MRR80 mode with have a max unambiguous velocity of 55kmph
 * and the other having a max unambiguous velocity of
 * (55/1.2) kmph, and then use the 'chinese remainder
 *  theorem' to estimate the true velocity.
 *
 * The MRR80 consists of one profile, two kinds of chirps,
 * with each chirp being repeated 64 times. These two sets of
 * chirps are processed seperately. The estimate of velocity
 * in one set, is compared with the estimate in the other set
 * to generate the true velocity. Only one tx is active in
 * this mode. i.e. No MIMO is used in MRR80.
 *
 * USRR20 consists of one profile (much higher BW MRR80), two
 * chirps (in a TDM-MIMO configuration), processed as a conventi-
 * nal two-tx four-rx capture. Some improvements to the max-
 * velocity is done so that we can still maintain a reasonable 
 * 36kmph max velocity.
 *
 * Since the chirp design of MRR80 and USRR20 are  different 
 * two different 'processing paths' are used to process them. 
 * 
 * USRR20 is processed by POINT_CLOUD_PROCESSING path and 
 * MRR80 is processed by the MAX_VEL_ENH_PROCESSING path.
